What is Mineral Processing?

Mineral processing (also called ore dressing or beneficiation) involves separating valuable minerals from waste rock (gangue) to produce concentrated material for metallurgical or industrial use.

Key Stages in Mineral Processing

1. Comminution
– Crushing & grinding ore into smaller particles to liberate minerals.
– Equipment: Jaw crushers, ball mills, SAG mills.

2. Classification
– Sorting particles by size (e.g., screens, hydrocyclones).

3. Separation Techniques
– Gravity Separation: Uses density differences (e.g., jigs, spirals).
– Magnetic Separation: For iron-bearing minerals (e.g., magnetite).
– Froth Flotation: Chemicals make minerals hydrophobic for air bubble attachment.
– Leaching: Dissolving metals using solvents (e.g., cyanide for gold).

4. Dewatering
– Removing water from concentrates (thickeners, filters, dryers).

5. Tailings Management
– Safe disposal of waste materials to minimize environmental impact.
