University of Oulu Mining Engineering, Mineral Processing and Geophysics Master's Thesis Guide: 491601S, Maturity Test and Laturi

Quick answer: the exact thesis route

The University of Oulu programme is Mineral Resources and Sustainable Mining: Mining Engineering, Mineral Processing and Geophysics, a two-year 120 ECTS Master of Science (Technology). The exact 2026-2027 Peppi programme is 50946 / IMP2026MRSMMEMPG. Its common thesis module is 50947 / IMP2026MRSMMEMPG-1001, containing 491601S Master’s Thesis, 30 ECTS, and 491600S Maturity Test, 0 ECTS.

1. What this guide covers

This guide is bounded to the verified 2026-2027 curriculum, the common thesis and maturity objects, the three study options, current realization records, Laturi, and subject-specific research methods. It separates Mining Engineering, Mineral Processing and Geophysics because their data, software, fieldwork and analytical assumptions differ substantially. The guide also preserves the 2027-2030 curriculum transition boundary so later cohorts know which administrative facts need fresh verification.

2. Programme size and structure

The current Peppi root 50946 / IMP2026MRSMMEMPG resolves to exactly 120 ECTS. The structure includes the 30 ECTS thesis/maturity module, 15 ECTS of common mining-related studies, a 45 ECTS specialisation block, 5 ECTS of compulsory language or other studies, and 25 ECTS of free-choice other studies. Students should still use their approved personal study plan when checking which courses satisfy their individual degree.

3. The three study options

The verified 2026-2027 structure offers Mining Engineering, Mineral Processing, and Geophysics. Their 45 ECTS specialisation modules are objects 50951, 50952, and 50954. All three use the same 491601S thesis code, but the evidence base and method can be very different. A geophysical inversion thesis is not evaluated like a flotation experiment, and a mine-design thesis is not designed like either of them.

4. Exact thesis object: 491601S

The exact thesis is 491601S Master’s Thesis, Peppi object 10249, worth 30 ECTS. The current realization is 491601S-3007, running from 1 August 2026 to 31 July 2027. The course is offered in Finnish and English and belongs to Mining Engineering and Mineral Processing in the subject metadata while its content explicitly covers mining engineering, mineral processing technology and applied geophysics thesis topics.

5. When the thesis can start

The thesis course says the master’s thesis can be started when most of the master’s degree studies have been completed. This is practical rather than arbitrary. Advanced courses supply field-specific theory, software and analytical methods that the thesis may require. Students should therefore check both formal readiness and methodological readiness: having the right study record does not automatically mean the proposed research can be executed safely and competently.

6. Topic approval and supervision

The thesis topic is agreed with the professor of the relevant subject: mining engineering, mineral processing technology or applied geophysics. Other supervisors or advisers may participate from inside or outside Oulu Mining School, but one supervisor must be internal. The programme person in charge must also be informed about the topic. This creates a clear academic anchor even when the work is company commissioned or highly specialised.

7. Supported thesis forms

491601S allows several research forms. The thesis may include fieldwork, research in a mine or enrichment facility, laboratory work, questionnaire research, or theoretical work. Every thesis also includes familiarisation with scientific literature and preparation of the written master’s thesis. The method should therefore be selected because it answers the research problem, not because one approach is assumed to be mandatory across the programme.

8. Final seminar presentation is embedded in the thesis

The exact thesis course states that the written thesis is evaluated through the Degree Programme Committee process and that, in the final stage, the thesis is presented in a seminar. The 2026-2027 programme tree does not show a separate credited thesis-seminar course inside module 50947. The safe interpretation is therefore an embedded seminar presentation requirement, not an extra invented seminar code or ECTS amount.

9. Thesis assessment and grading

The written thesis is evaluated in the Degree Programme Committee meeting based on the statement of the appointed examiners or supervisors. The course uses the 1-5 or failed grading scale. Examiners are appointed by the person in charge of the master’s programme on the proposal of the professor of the subject. Students should leave time for examiner statements and committee handling instead of planning graduation immediately after uploading a manuscript.

10. Laturi and the formal thesis record

The final thesis is uploaded through the University of Oulu Laturi system. Laturi is part of the formal assessment and publication route, so the final document must be suitable for academic evaluation and any public-access rules that apply. Company or site confidentiality should be resolved before this point. Do not rely on a last-minute attempt to remove sensitive information after the thesis has already been written around it.

11. Exact maturity test: 491600S

The exact maturity course is 491600S Maturity Test, Peppi object 6135, worth 0 ECTS. The current realization is 491600S-3006, running from 1 August to 25 October 2026. The course is graded Pass/Fail and is completed after the master’s thesis. Because realization periods can be shorter than the thesis realization, students should verify the live maturity record when preparing to graduate.

12. The thesis abstract is the current maturity mechanism

Under the current 491600S wording, the abstract written for the master’s thesis and uploaded to Laturi is accepted as the maturity test. The professor of the study field or the thesis supervisor evaluates it. This is different from programmes where maturity is normally a separate Exam-system essay. Do not import another programme’s maturity procedure into this one.

13. Finnish and Swedish language-history rules still matter

The current course also preserves the legal language-history boundary. If Finnish or Swedish proficiency has not already been demonstrated in the earlier degree, the maturity requirement may also need to demonstrate that language proficiency. Students educated in Finnish or Swedish may need a corresponding Finnish or Swedish abstract in addition to English when the thesis is written in English. Confirm the individual rule before final upload.

14. Mining Engineering: research environment

The Mining Engineering option combines rock mechanics, drilling, blasting, mine planning, excavation, support, ventilation, transport, economics, automation and mining geophysics. Thesis work can therefore range from design calculations and operational improvement to monitoring, digital mine models or economic evaluation. The first methodological task is to define the mine system, geometry, material behaviour, operational objective and evidence that will be used to judge whether a proposed improvement actually works.

15. Rock mechanics and stability

491686S Advanced Rock Mechanics supports analysis of rock excavation, tunnelling, slope stability, rock support, deep mining and underground stability. A thesis using rock-mechanics evidence should document the rock-mass classification, material parameters, discontinuities, geometry, stress assumptions and support conditions. If a numerical or analytical stability result is used, explain how parameters were obtained and whether sensitivity or uncertainty checks change the engineering recommendation.

16. Mine planning and operations

492600S Mining Engineering covers mine layout, development, drilling, blasting, ventilation, loading and transportation, open-pit and underground methods, support, safety, economy, automation and digitalisation. A mine-planning thesis should state the design objective, reserve or block-model basis, production assumptions, equipment constraints and safety boundaries. A technically feasible layout is not automatically economically or operationally optimal, so evaluation criteria must be explicit.

17. Rock blasting research

492608S Rock Blasting supports blast design, fragmentation, burden and spacing, stemming, primer placement, delay timing, specific charge and vibration control. A blasting thesis should document explosive and initiation system, blast geometry, rock conditions, monitoring method and performance metrics. Fragmentation, vibration, dilution, recovery, safety and cost can move in different directions, so one successful indicator does not prove the overall blast design is optimal.

18. Digital mine design and scheduling

492609S Software Application in Mining Engineering supports digital design of polylines, tunnels, declines, ramps, stopes and drillholes, plus block-model queries, stope reconciliation and schedule dependencies. These are strong programme-supported digital methods, but software output is only as reliable as the geological, geometric and operational inputs. Record model versions, design assumptions, attribute rules and scheduling constraints when they affect the thesis result.

19. Mining economics and project valuation

492602S Financial and Project Valuation of Mining covers time value of money, inflation, taxation, capital investment, financing, depreciation, financial statements and project risk. Economic theses should state price assumptions, cost basis, discount rate, taxation treatment, production schedule and uncertainty. NPV or IRR values are conditional on those inputs. Sensitivity or scenario analysis is essential when one uncertain variable can reverse the investment conclusion.

20. Mineral Processing: research environment

The Mineral Processing option focuses on ore beneficiation, comminution, flotation, gravity and other separation methods, process mineralogy, concentrate quality, process modelling, scale-up and process development. Theses may be experimental, computational or integrated. The crucial boundary is scale: laboratory recovery, locked-cycle testing, pilot operation and full plant performance are not interchangeable evidence. State clearly which scale the result represents.

21. Beneficiation experiments and mass balances

493605S Ore Benefication Technologies covers mineral characterisation, comminution, flotation, gravity separation, sedimentation, optimisation, sampling and mass-balance calculations. Experimental theses should report feed characteristics, sample preparation, test conditions, replicate strategy and analytical methods. Recovery and grade must be interpreted together, and mass-balance closure provides an important quality check when material streams are measured independently.

22. HSC Sim and process modelling

491687S Process Modeling in Mineral Processing explicitly uses HSC Sim to model mineral processes, flowsheets, flotation, comminution, thickening, dynamic behaviour and scale-up from laboratory results. HSC Sim is therefore a supported thesis tool, not a universal requirement. A modelling thesis should document model structure, parameter sources, calibration, input distributions and how simulation outputs were checked against laboratory or plant evidence.

23. Flowsheet development and scale-up

493608S Development of Benefication Processes takes students from mineralogy and laboratory tests to process-circuit design, continuous testing, scale-up and realistic flowsheet selection. A thesis following this route should distinguish what was directly measured from what was estimated during scale-up. Equipment sizing, recovery assumptions, recycle streams and mass balances must remain internally consistent. Alternative flowsheets should be compared using the same feed and performance basis.

24. Concentrate quality and economic value

493607S Quality Requirements for Concentrate connects concentrate quality with downstream processing, penalty elements, price clauses and Net Smelter Return. A thesis that optimises only recovery may overlook concentrate specifications or economic penalties. Report the mineralogical and chemical quality metrics that matter for the intended product and explain how technical improvements translate, or fail to translate, into economic value.

25. Mathematical modelling and process control

TP00AQ18 Modelling and control for industrial processes supports mechanistic and data-driven models, optimisation and process control, including Matlab/Simulink in relevant modules. In mineral-processing applications, models can address crushing, grinding, flotation, leaching and separation. Matlab or Simulink is not compulsory for every thesis. When used, document equations or model architecture, training or calibration data, constraints and performance metrics.

26. Geophysics: research environment

The Geophysics option combines electrical and electromagnetic methods, seismic soundings, potential fields, airborne geophysics, GIS, mining geophysics and mine geology. Theses may involve field acquisition, processing, inversion, interpretation or integration of several datasets. The central methodological task is to connect a physical property contrast to a geological or engineering question. Geophysical anomalies are observations, not automatic proof of one subsurface interpretation.

27. Electrical and EM methods

494601S Electrical and EM-methods I supports electrical resistivity, induced polarization and self-potential surveys, including field work, digital processing and inversion. A thesis should document electrode or sensor geometry, survey layout, acquisition settings, topography treatment, preprocessing, inversion parameters and data-quality rules. Interpretation should distinguish measured response, inversion result and geological inference so uncertainty is not hidden by a visually smooth model.

28. Seismic and mine-seismology evidence

The Geophysics curriculum includes 494604S Seismic soundings, while 493301A Mining Geophysics introduces mining seismology and monitoring of seismicity and rock bursts using real digital data. A seismic thesis should state acquisition geometry, timing or velocity assumptions, processing sequence and interpretation criteria. In mine-seismic studies, event-detection thresholds, catalogue completeness and spatial uncertainty can materially affect conclusions about hazard or rock-mass behaviour.

29. EPISODES and digital mining-geophysics data

Mining Geophysics uses the EPOS EPISODES distributed platform for practical work with anthropogenic-hazard data. This demonstrates that programme-supported thesis methods can include remote digital datasets and platform-based analysis, not only field campaigns. If a thesis uses a shared repository, record dataset version, event selection, preprocessing, software or application used and any filtering decisions so another researcher can understand what was actually analysed.

30. Magnetic, gravity and airborne methods

494605S and 494606S Potential Fields and Airborne Geophysics support magnetic, radiometric, gravity and airborne electromagnetic data, together with modelling and inversion. Potential-field interpretation is non-unique: different subsurface property distributions can fit similar observations. A thesis should therefore state density or susceptibility assumptions, regional-field treatment, model constraints and independent geological evidence used to narrow the interpretation.

31. GPR and near-surface investigations

494607S GPR soundings covers ground-penetrating radar theory, field measurement, processing and interpretation. GPR performance depends strongly on antenna frequency, material conductivity, moisture, survey geometry and processing choices. A thesis should report acquisition parameters and explain the depth-resolution trade-off. Processed radargrams can make interfaces look precise, but interpretation should remain bounded by signal quality, velocity assumptions and ground truth.

32. GIS is an integration tool, not proof by itself

The Geophysics option includes 494603S GIS applications. GIS can combine drilling, geology, geophysics, topography, infrastructure and environmental information, but overlaying layers does not automatically establish a causal relationship. Define coordinate reference systems, spatial resolution, interpolation or classification rules and temporal consistency. When several layers are combined into a prospectivity or risk map, explain weighting and validation rather than presenting the final map as self-evident.

33. Geometallurgy links geology to processing

772694S Geometallurgy and Mineral Processing connects ore geology, process mineralogy, mineral processing, modelling and simulation. It supports quantitative geometallurgical data analysis and design of sampling and research campaigns. A geometallurgical thesis should preserve sample representativeness across spatial domains and ore types. Relationships between mineralogy and process response can be useful for planning only when sampling, analytical precision and scale are adequate.

34. Environmental geochemistry and mine water

774636S Geochemistry of Mining Environment supports prediction and monitoring of mining impacts on soil and water, including acid mine drainage, static and kinetic testing and geochemical modelling such as PHREEQC. A thesis should document sample type, analytical method, water chemistry, mineralogical context and model assumptions. Long-term predictions require particular care because weathering rates, hydrology and mineral availability can change over time.

35. Portable and on-site geochemical methods

772702S On-site and surface geochemical techniques covers portable and manual geochemical and mineralogical methods, including XRF-related field work. Portable measurements can improve spatial coverage but still require calibration, radiation-safety compliance, matrix awareness and quality control. A thesis should state instrument model, calibration or reference material, measurement duration, surface preparation and how field values were checked against laboratory evidence when relevant.

36. Mining feasibility integrates the whole value chain

492603S Mining Project Feasibility Study integrates mineral-resource confidence, mining, processing, waste and water management, closure, infrastructure, permitting, social impacts, ESG, costs and financial evaluation. A feasibility thesis should identify the study stage and confidence level. Scoping, prefeasibility and feasibility studies do not support the same level of decision certainty. Technical and economic assumptions should be traceable to evidence rather than hidden inside one financial spreadsheet.

37. CAPEX, OPEX, NPV and IRR need transparent assumptions

Feasibility analysis may use CAPEX, OPEX, NPV, IRR and payback period. These metrics are useful only when the underlying production schedule, recovery, commodity price, exchange rate, tax, discount rate and closure assumptions are visible. A thesis should test material uncertainties and avoid presenting one deterministic base case as a forecast. If ESG or permitting assumptions affect timing or cost, include them explicitly in the scenario logic.

38. Laboratory, pilot and plant evidence are different

Mineral-processing and mining theses often combine evidence collected at different scales. Laboratory tests offer control, pilot tests improve process realism, and plant data reveal operational variability. Do not merge them without explaining scale-up. Report which conditions change with scale, including residence time, mixing, particle-size distribution, equipment geometry, recycle streams or operator control. A successful laboratory result is evidence of potential, not automatic proof of full-scale performance.

39. Sampling and representativeness

Sampling is central across ore characterisation, geometallurgy, environmental geochemistry and process testing. A thesis should explain population or material domain, sample locations, masses, increments, compositing and preparation. Heterogeneous ore or waste can produce large sampling error even when laboratory analysis is precise. Where conclusions concern a mine block, stockpile, tailings facility or catchment, the sampling design must match that spatial and material scale.

40. Calibration, validation and uncertainty

Models used in geophysics, mineral processing, rock mechanics or project economics should separate calibration, validation and uncertainty. Calibration adjusts a model against reference evidence; validation tests performance against independent or withheld evidence; uncertainty analysis examines how imperfect knowledge changes outputs. A good visual fit is not enough. Report evaluation metrics and identify which assumptions dominate the final engineering or economic recommendation.

41. Safety is part of the method boundary

Mining Engineering research may involve blasting, underground access, heavy equipment, radiation-producing instruments, field sites or industrial plants. The thesis should not treat safety as an administrative afterthought. Follow site and University procedures, define who authorises access and equipment use, and ensure that data collection does not require unsafe deviations from normal operation. If safety constraints limit the sample or experiment, state that limitation in the methodology.

42. Company and industry collaboration

The thesis course explicitly allows topics from Oulu Mining School research groups, mining-related companies and the student’s own proposal. Industry collaboration can provide real sites, data and engineering relevance, but the university supervisor and academic assessment remain decisive. Agree data ownership, publication rights, intellectual property, access schedules and review responsibilities early. Commercial usefulness should support, not replace, transparent scientific reasoning.

43. Confidential site and company data

Mine plans, orebody models, production data, cost structures, process parameters and geophysical coordinates can be commercially or security sensitive. Before analysis, classify what may enter the public thesis. Aggregation, redaction, anonymised coordinates or derived indicators can sometimes preserve scientific value, but only if the method remains reproducible enough for assessment. Do not put restricted information in an appendix and assume publication systems will hide it.

44. Questionnaire or interview research has extra obligations

491601S explicitly permits questionnaire research. If a thesis interviews workers, experts or community members, or surveys people about mining impacts, safety, acceptance or work practices, the project also enters human-participant and personal-data territory. Define recruitment, consent, recording, identifiers, retention and access before collection. Formal ethics-committee review is not automatic for every mining thesis, but privacy and ethical classification must be handled early.

45. Environmental and closure claims need a defined system boundary

Claims about sustainable mining, reduced environmental impact or improved closure performance require a defined comparison. State the mine stage, spatial boundary, time horizon and indicators. A process that reduces one waste stream may increase energy, water or reagent use elsewhere. Unless the thesis performs a full system or life-cycle analysis, describe the specific impact measured rather than implying that one improvement proves overall sustainability.

46. Research integrity and reproducibility

Responsible mining research requires traceable data, calculations and interpretation. Preserve raw data where permitted, document cleaning and exclusion rules, keep scripts or model settings where they determine results, cite software and datasets, and record material deviations from the research plan. Negative results or poor model fit should not be hidden. Reproducibility does not mean every confidential dataset must be public; it means the analytical path must be transparent enough to evaluate.

47. Responsible use of AI

AI may assist coding, literature discovery, data cleaning, modelling support or drafting only within current University rules and the thesis method. Do not upload confidential mine, company or personal data to external systems without an approved basis. Verify generated code and calculations against known cases, preserve provenance for important outputs and disclose material use where required. The student remains responsible for engineering judgement and scientific conclusions.

48. Graduation is a separate administrative stage

A finished manuscript is not the same as a completed degree. The thesis must pass examiner and Degree Programme Committee handling, the maturity requirement must be completed, study registrations must be correct and the student must follow the current graduation procedure. Plan backwards from the desired graduation date and allow time for revisions, Laturi handling and committee schedules. Administrative deadlines can change by academic period.

49. Recheck the 2027-2030 curriculum

This guide is anchored to 50946 / IMP2026MRSMMEMPG for 2026-2027. University transition rules mean later cohorts should recheck the programme root, study-option modules, thesis and maturity realizations and course names before relying on exact codes here. The research-design principles remain useful, but administrative details should always follow the student’s own curriculum and the live Peppi record.

50. Final pre-submission checklist

Before final submission, verify the live 50946 programme, your specialisation, 491601S thesis and 491600S maturity records; confirm internal supervision and topic approval; make the research method match the study-option question; document sampling, software, model assumptions, calibration and uncertainty where relevant; resolve safety, company confidentiality, participant privacy and ethics; present the thesis in the required final seminar; upload the publication-safe thesis and abstract to Laturi; then follow examiner, committee and graduation procedures.

51. Choose the method from the claim, not the study option label

The three specialisations provide different toolboxes, but the thesis method should still be selected from the claim the student needs to support. A Mining Engineering thesis may require geophysical data; a Mineral Processing thesis may need economic evaluation; a Geophysics thesis may depend on mine-design or geological constraints. Interdisciplinary evidence is legitimate when each dataset and model has a defined role. Write the method so a reader can trace every important conclusion back to the observation, calculation or assumption that supports it.
