◆ From Ore to Metal

Adding Value at Every Step

THE ROUTE

Ore to metal in nine stages

Step 1: Mine

Step 2: Crushing

Step 3: Grinding

Step 4: Screening

Step 5: Beneficiation

Step 6: Concentrate

Step 7: Smelting

Step 8: Refining

Step 9: Metal

THE METHODS

Separation & extraction techniques

Physical Separation

Size reduction, screening and classification to separate minerals based on physical properties.

Gravity Separation

Separation of heavy minerals from lighter gangue using density differences in water or fluid.

Magnetic Separation

Removal of magnetic minerals from non-magnetic materials using magnetic force.

Flotation

Chemicals and air bubbles separate valuable minerals from gangue based on surface properties.

Leaching

Dissolving valuable minerals from ore using chemical solutions.

Hydrometallurgy

Extraction of metals from leach solutions through precipitation, solvent extraction or ion exchange.

Pyrometallurgy

Extraction of metals by high-temperature processes like smelting and roasting.

Electrowinning

Extraction of metals from solution by applying electric current to deposit pure metal.

SX-EW

Solvent Extraction + Electrowinning

A modern, efficient route for producing high-purity metals.
