Geostatistics: Applying statistical methods to estimate mineral reserves.
Exploration Techniques: Using geophysical (seismic, magnetic) and geochemical methods.
Mine Design and Planning:
Surface Mining Methods: Open-pit, strip mining, and quarrying.
* **Underground Mining Methods:** Room and pillar, cut-and-fill, longwall, and block caving.
* **Mine Ventilation and Airflow Control:** Ensuring safe air quality and temperature.
* **Rock Mechanics and Ground Control:** Analyzing rock stress and designing stable slopes and tunnels.
Mining Operations:
Drilling and Blasting: Methods for breaking up rock.
Excavation and Loading: Equipment like shovels, loaders, and draglines.
Haulage and Transportation: Trucks, conveyors, and rail systems.
Mine Safety and Health: Hazard identification, risk assessment, and regulations.
Sustainability and Environment:
Mine Waste Management: Handling and disposal of tailings and waste rock.
Mine Reclamation and Closure: Restoring the land after mining operations cease.
Acid Mine Drainage (AMD) Mitigation: Preventing and treating acidic water discharge.
Extractive (Chemical) Metallurgy and Mineral Processing
This area deals with recovering valuable minerals from the ore and refining them into a pure metal or usable material.
Mineral Processing (Mineral Dressing)
Comminution: Crushing, grinding, and milling to reduce particle size.
Classification and Screening: Separating particles by size.
Separation Techniques:
Flotation: Chemically separating valuable minerals from waste (gangue).
Gravity Separation: Using density differences (e.g., jigs, tables).
Magnetic and Electrostatic Separation: Using electrical or magnetic properties.
Dewatering: Thickening, filtering, and drying to remove water.
Extractive Metallurgy
Pyrometallurgy: Processes involving high temperatures.
Roasting and Calcination: Heating to cause chemical change.
Smelting: Melting the concentrate to separate metal from slag (waste).
Hydrometallurgy: Processes involving aqueous (water-based) solutions.
Leaching: Dissolving the metal out of the ore using chemical solutions (e.g., cyanide or acid).
Solvent Extraction and Ion Exchange: Purifying the dissolved metal solution.
Precipitation and Electrowinning: Recovering the metal from the solution.
Electrometallurgy: Processes using electrical energy, typically for refining.
Electrorefining: Using electrolysis to produce high-purity metals.
Electrowinning: Recovering metals from leach solutions.
Metallurgical Thermodynamics and Kinetics: The study of energy and rate of chemical reactions in metal production.
Physical and Mechanical Metallurgy & Materials Engineering
This domain focuses on the structure, properties, manufacturing, and performance of materials, particularly metals and alloys.
Materials Structure and Characterization:
Crystallography: Study of crystal structures (BCC, FCC, HCP).
Microstructure Analysis: Using techniques like Scanning Electron Microscopy (SEM) and X-ray Diffraction (XRD).
Phase Transformations: Changes in a material's structure with temperature or pressure (e.g., in steel).
Mechanical Properties:
Stress, Strain, and Elasticity: Analyzing material response to force.
Hardness, Toughness, and Ductility: Key mechanical measures.
Fracture and Fatigue: Understanding how materials fail under static or cyclic loading.
Creep: Deformation under constant stress at high temperatures.
Material Processing and Manufacturing:
Casting: Pouring molten metal into a mold (e.g., sand casting, die casting).
Metalworking/Forming: Shaping solid metal (e.g., forging, rolling, extrusion).
Heat Treatment: Controlled heating and cooling to change mechanical properties (e.g., annealing, quenching, tempering).
