Mineral Processing & Metallurgy learning path: everything to study, topic by topic

Determining mineralogy, liberation, grade, and metallurgical response of an ore to guide processing route selection.

Arranging unit operations into a coherent processing flowsheet that balances recovery, grade, cost, and operability.

Understanding the recovery-grade relationship and how to balance metal recovery against concentrate grade for value maximization.

Applying correct sampling theory and assay methods to obtain representative, low-bias data for metallurgical decisions.

Selecting and operating crushers to reduce run-of-mine ore to a feed size suitable for downstream grinding.

Operating tumbling and stirred mills to achieve target grind size and mineral liberation at acceptable energy cost.

Using hydrocyclones and screens to separate particles by size and close the grinding circuit efficiently.

Estimating and optimizing the energy consumed in size reduction, the dominant cost driver in most plants.

Separating minerals by surface chemistry using collectors, frothers, and modifiers in flotation cells and columns.

Concentrating minerals by differences in density using jigs, spirals, shaking tables, and centrifugal concentrators.

Separating minerals by magnetic susceptibility using low- and high-intensity magnetic separators for iron and industrial minerals.

Pre-concentrating ore by sink-float in a dense medium to reject gangue before fine grinding and downstream concentration.

Dissolving target metals from ore or concentrate into solution using acid, cyanide, or other lixiviants under controlled conditions.

Purifying and concentrating a metal from leach solution by selective extraction and stripping between aqueous and organic phases.

Recovering metal from purified solution by precipitation, cementation, or electrowinning into a saleable product.

Melting concentrate at high temperature with fluxes to separate metal from slag and produce a matte or crude metal.

Thermally treating concentrate below melting point to oxidize, drive off sulfur or volatiles, and prepare feed for downstream steps.

Purifying crude metal to market specification by fire refining or electrorefining to remove residual impurities.

Concentrating slurry solids by gravity settling in thickeners, aided by flocculants, to recover water and prepare feed for filtration.

Dewatering thickened slurry through pressure or vacuum filters to produce a transportable cake and recover process water.

Maximizing process water recovery and managing tailings deposition safely and in line with environmental requirements.

Deploying sensors, analyzers, and control loops to stabilize and automate plant operation in real time.

Reconciling mass and metal balances across the plant to produce auditable production figures and detect losses.

Defining and acting on key performance indicators to drive continuous improvement of recovery, throughput, and cost.
