Mineral Engineering Syllabus

Engineering Mathematics

Calculus, differential equations, matrices, numerical methods, probability, statistics and optimisation support analysis and quality.

Engineering Physics and Chemistry

Physics explains mechanics, heat and measurement. Chemistry supports materials, corrosion, lubricants and surface treatment.

Engineering graphics

Students learn projections, sections, dimensioning, tolerances and drawing standards. Drawings communicate component intent to materials and inspection.

Engineering mechanics

Statics and dynamics cover forces, motion, work and energy. These foundations support machines and processes.

Strength of materials

Stress, strain, bending, torsion and failure help engineers design parts, tools and fixtures safely.

Material science

Students study metals, polymers, ceramics and composites, including structure, properties and processing. Material selection connects performance with manufacturability and cost.

Metallurgy and heat treatment

Phase diagrams, solidification, microstructure, annealing, hardening and tempering explain how processing changes metals.

Mineral beneficiation

Beneficiation prepares ore by crushing, grinding, sizing and separating valuable minerals from gangue. Methods may use gravity, magnetic, electrostatic or flotation principles. Engineers study recovery, grade, water, energy, tailings and representative sampling.

Metallurgical thermodynamics and kinetics

Thermodynamics predicts whether reactions and phase changes are possible, while kinetics explains their rate. Activity, equilibrium, free energy, diffusion, nucleation and reaction control help engineers select temperature, atmosphere, time and reactor conditions.

Transport phenomena

Momentum, heat and mass transfer determine mixing, reaction, solidification, furnace performance and pollutant movement. These principles connect laboratory chemistry with industrial equipment.

Pyrometallurgy

Pyrometallurgy uses high-temperature operations such as roasting, calcination, smelting and refining. Students learn furnace types, fuels, refractories, slags, gas handling, heat balance and process safety.

Hydrometallurgy and electrometallurgy

Hydrometallurgy uses leaching, purification and solution recovery, while electrometallurgy uses electrical energy for extraction or refining. Students compare selectivity, energy, reagent use, waste and purity.

Ironmaking and steelmaking

Students study raw materials, coke, sinter or pellets, blast-furnace principles, direct reduction, basic oxygen steelmaking, electric furnaces, secondary metallurgy and continuous casting. Chemistry, temperature and inclusion control influence steel quality.

Non-ferrous extractive metallurgy

Extraction and refining routes for aluminium, copper, zinc, lead, nickel, titanium and other metals differ because their ores and chemical behaviour differ. Process choice must consider energy, emissions, by-products and recycling.

Physical and mechanical metallurgy

Crystal structure, defects, diffusion, phase transformations and solidification explain microstructure. Dislocations, strengthening, fracture, fatigue, creep and metal working connect microscopic mechanisms with component performance.

Corrosion and protection

Corrosion is electrochemical degradation affected by material, environment and design. Students study corrosion forms, testing, material selection, coatings, inhibitors and cathodic protection. Control should address the cause rather than only repainting damage.

Mineralogy and ore microscopy

Mineralogy identifies valuable minerals, gangue, alteration products and harmful impurities. Students use hand specimens, microscopy, diffraction or other analytical methods according to laboratory availability. Texture and association matter because two ores with the same chemical grade may respond differently during grinding and separation.

Sampling and sample preparation

Representative sampling is fundamental to mineral engineering. Students learn increments, composite samples, sample mass, particle-size effects, bias, contamination, moisture control, splitting and preparation. A precise assay cannot repair a biased sample, so sampling design must match the decision being made.

Comminution

Comminution uses crushing and grinding to reduce particle size and liberate valuable minerals. Students compare jaw, gyratory, cone, roll, impact and tumbling equipment, along with newer energy-efficient technologies where available. They study reduction ratio, circulating load, power, wear, overgrinding and the relationship between liberation and cost.

Screening and classification

Screens separate mainly by particle size, while classifiers use settling behaviour in a fluid. Aperture, vibration, bed depth, feed rate, density, viscosity and particle shape affect performance. Classification efficiency influences grinding-circuit capacity and prevents unnecessary production of fines.

Gravity concentration

Gravity methods exploit differences in density and particle movement. Jigs, spirals, shaking tables, dense-medium systems and centrifugal devices may be studied. Performance depends on liberation, size range, density contrast, feed preparation and stable operating conditions.

Magnetic and electrostatic separation

Magnetic separation uses differences in magnetic response, while electrostatic methods use electrical properties. Students compare low- and high-intensity equipment, wet and dry operation, field strength, feed presentation and safety. Mineralogy and particle size determine whether these routes are technically suitable.

Froth flotation

Flotation separates particles through controlled surface chemistry. Students study collectors, frothers, modifiers, pulp chemistry, conditioning, air, mixing, froth behaviour and circuit arrangement. Recovery and concentrate grade must be evaluated together; increasing one can reduce the other.

Coal and industrial-mineral processing

Coal preparation may include crushing, sizing, dense-medium separation, spirals, flotation and dewatering. Industrial minerals often require careful control of purity, colour, particle shape, surface properties and contamination. Product specifications can be as important as overall recovery.

Dewatering

Thickening, clarification, filtration, centrifuging and drying reduce water in concentrates and tailings. Students examine settling, flocculation, permeability, moisture targets, water recovery and disposal. Dewatering is closely connected with transport, product handling and tailings safety.

Refractories and furnace materials

Refractories protect furnaces and vessels from heat, chemical attack and mechanical wear. Selection depends on temperature, slag chemistry, thermal cycling, installation and repair practice.

Particle characterisation

Particle-size distribution, shape, density, surface area, mineral liberation and chemical composition support circuit design and control. Students learn that every test has a sample requirement, detection limit and uncertainty. Results should be reported with method, basis and units rather than as isolated numbers.

Mineral-processing machinery

Students examine crushers, mills, screens, classifiers, separators, flotation cells, pumps, thickeners, filters, conveyors and feeders. Selection considers capacity, feed variability, wear, energy, water, control, maintenance access and safety. Equipment names alone are less important than understanding their operating principles and limits.

Process flowsheet development

A flowsheet connects unit operations through streams, recycle loads and product targets. Engineers begin with mineralogy and test work, then establish mass and water balances, equipment duties, control points and sampling locations. Alternative flowsheets are compared on recovery, grade, operability, cost and environmental performance.

Pilot-plant testing

Pilot work tests continuous behaviour, circulating load, residence time, reagent control, wear and variability. Scale-up must recognise differences between laboratory and industrial mixing, transport and heat or mass transfer. Teams define objectives and acceptance criteria before starting expensive trials.

Plant instrumentation

Flow, density, pressure, level, particle size, power and chemical measurements support control. Instruments need suitable installation, calibration, maintenance and validation. A dashboard is useful only when the underlying sample and sensor data are trustworthy.

Industrial engineering

Work study, plant layout, line balancing, ergonomics and componentivity help design efficient systems. Improvement should not overload workers or bypass safety.

Operations research

Linear programming, inventory, queuing, scheduling and simulation support decisions under constraints.

Mineral-production planning and control

Mine feed, stockpiles, blending, plant capacity, maintenance and product demand must be coordinated. Plans adapt to ore hardness, grade, mineralogy, weather, equipment availability and downstream requirements.

Quality engineering

Students learn control charts, capability, sampling, root-cause analysis, design of experiments and quality systems. Inspection alone cannot create quality.

Process capability

Capability compares process variation with specification limits after the process is stable. A high capability number cannot compensate for biased measurement or unstable data. Engineers first confirm measurement reliability and control.

Control charts distinguish normal variation from signals needing investigation. Adjusting a stable process after every small fluctuation can increase variation, while ignoring a trend can allow future failure.

Safety-critical, one-sided, non-normal or low-volume characteristics may need different analysis. Results require adequate sample size and engineering context.

Metallurgical accounting and measurement systems

A mineral measurement system includes sampler, preparation method, laboratory instrument, operator, environment and software. Repeatability, bias and reconciliation studies examine whether measurement variation is small enough for the production and recovery decision.

If an instrument cannot reliably distinguish good from bad parts, additional inspection will not solve the problem. Calibration and measurement-system analysis serve related but different purposes.

Design of experiments and plant troubleshooting

Design of experiments changes factors systematically to identify effects and interactions. Engineers define responses, ranges, replication and safety boundaries before testing.

Plant troubleshooting preserves evidence, defines the loss and investigates feed changes, sampling, equipment, control, reagent, water and operating practice. Teams should avoid blaming an operator before examining mineral variability, unclear procedures, worn components and unrealistic throughput targets.

Maintenance engineering

Preventive, predictive and corrective maintenance support availability. Condition monitoring uses vibration, temperature, oil or electrical data where suitable.

Reliability and equipment effectiveness

Reliability engineering examines failure frequency, repair time, critical spares and preventive tasks. Plans should reflect risk and evidence rather than servicing every component at the same interval.

Overall equipment effectiveness combines availability, performance and quality to show major plant losses. Manipulating planned time or ignoring short stops makes it misleading.

After safe recovery from breakdown, teams record symptoms, alarms, operating condition and recent changes. Replacing the failed part restores operation but may not address lubrication, alignment, contamination or overload that caused it.

Automation

Sensors, actuators, programmable controllers, drives and control logic automate crushing, grinding, separation, dewatering and material handling. Safe guarding, interlocks and manual recovery are essential.

Robotics

Remote machines and robots can support sampling, inspection, hazardous-area work and maintenance. Students study sensing, programming, communication, task limits and safety where the curriculum provides this exposure.

Computer-integrated mineral processing

Integrated plant systems connect geology, mine planning, stockpiles, laboratory results, processing equipment, maintenance and business information. Integration requires reliable data definitions and controlled interfaces.

Sensor-based ore sorting

Sensor-based sorting uses measured particle properties such as colour, density response or X-ray characteristics to reject waste or separate ore before fine grinding. Its value depends on liberation at coarse size, detection reliability, throughput and the economic benefit of early rejection.

Digital mineral processing

Connected machines, industrial IoT, analytics, digital twins and plant-information systems support visibility and decisions. Cybersecurity and data quality are important.

Shop-floor data and traceability

Mineral-processing records may include ore source, stockpile, sample, laboratory result, equipment state, set point, reagent, water, product and tailings data. Traceability should match process and compliance needs; collecting every possible signal without a defined purpose creates cost and confusion.

Sensors need calibration, synchronised time and clear units. Missing or overridden values should be visible. A dashboard cannot replace verification of the physical process.

Digital work instructions can control revisions and show checks. Offline and recovery procedures are required when networks fail. Access control prevents unauthorised parameter changes.

Digital twins

A digital twin is a maintained digital representation connected to a physical asset or process. It may support simulation, monitoring, prediction or training. A static three-dimensional model is not automatically a digital twin.

The model needs a defined purpose, validated assumptions, reliable data and version control. Complex twins can cost more to maintain than the value they provide.

Operational-technology cybersecurity

Connected controllers and industrial computers create cyber risk. Segmentation, controlled remote access, backups, updates, account management and incident plans are important.

Plant availability and safety influence security decisions. Updates need testing and scheduled deployment. Students should test only authorised laboratory systems.

Simulation

Comminution, classification, separation, flotation, water-balance and whole-plant simulations help compare options. Models depend on assumptions and must be validated with representative test or operating data.

Wear and materials selection

Crushers, mills, pumps, cyclones and pipelines operate under abrasion, impact, corrosion and erosion. Students compare liners, grinding media, elastomers, ceramics and protective materials according to service conditions, replacement cost and safety.

Mineral processing systems design

Students compare flowsheet layouts, parallel trains, recycle streams, stockpiles and surge capacity. Ore variability, throughput, recovery, maintainability, water and investment guide selection.

Lean materials

Lean methods can reduce waiting, spillage, excess movement, unstable work and repeated sampling through observation, standard work and problem-solving. Lean should not mean removing necessary people, maintenance time or safety buffers blindly.

Supply chain

Procurement, logistics, reagents, spares, product transport and inventory affect mineral operations. Resilience requires qualified alternatives, traceability and risk assessment.

Supplier development

Supplier development begins with clear equipment, reagent, wear-part, capacity and quality expectations. Engineers review process duty, material compatibility, measurement, maintenance support, safety and change control.

Incoming inspection cannot compensate indefinitely for an incapable supplier. Joint root-cause work is more sustainable than sorting every shipment, though critical risks may still need source inspection.

Second sources reduce interruption risk but require qualification. Material described by the same generic grade may differ in route, surface or consistency. Substitution needs controlled approval.

Inventory and material flow

Inventory protects against variation but ties up cash, space and obsolescence risk. Engineers analyse lead time, demand, reliability and batch size rather than applying one rule everywhere.

Material handling should prevent mixing, damage and unsafe lifting. Point-of-use storage can improve flow when replenishment is reliable.

Cost engineering

Cost includes mining and feed preparation, labour, equipment time, wear parts, energy, water, reagent, laboratory work, maintenance, waste, overhead and lifecycle obligations. Engineers compare alternatives without ignoring closure or environmental risk.

Sustainable materials

Students study material efficiency, energy, water, emissions, repair, remanufacture and recycling. Environmental improvement needs measured baselines.

Reprocessing, recycling and secondary resources

Mine waste, tailings, slags, electronic waste and other secondary resources may retain valuable minerals or metals. Engineers characterise the material before selecting physical, chemical or combined recovery routes.

Variable feed condition makes reprocessing difficult. Weathering, oxidation, fine particles and historical chemicals can change behaviour. Projects need representative sampling and must avoid disturbing stable waste without geotechnical and environmental assessment.

Recovery can retain embedded value and reduce new extraction, but excavation, transport, water, energy, residue stability and liability must be considered. A resource estimate does not automatically make a reprocessing project viable.

Energy and resource accounting

Plants can meter electricity, fuel, compressed air, water and material by process or product. Normalising consumption against ore treated and valuable product distinguishes improvement from lower throughput.

Compressed-air leaks, idle machines, poor insulation and excessive scrap are common losses. Reducing energy must not undermine ventilation, cooling or safety.

Industrial waste hierarchy

Prevention is preferable to reuse, recycling, recovery and disposal. Engineers reduce offcuts, defects, expired material and unnecessary packaging before seeking a waste outlet.

Scrap segregation preserves value and prevents hazardous mixing. Recycling contracts need traceability and legal compliance.

Safety and ergonomics

Machine guarding, lockout, ventilation, lifting, fire and human factors are core. Safety must be designed into process and layout.

Research methods

Literature review, experimental design, statistics and technical writing support reliable projects.
