Run-of-mine ores are separated into valuable minerals and waste gangue by mineral processing to produce high grade minerals for industrial use. Generally, lump ore is treated by a float- sink separation known as dense medium separation, which is based on their density difference in a liquid. The conventional wet separations use large quantities of water.

Dry processing of iron ore presents an opportunity to eliminate costs and wet tailings generation associated with flotation and wet magnetic separation circuits. STET has evaluated several iron ore tailings and run of mine ore samples at bench scale pre-feasibility scale. Significant movement of iron and silicates was observed, with examples ...
Mineral processing also called 1-ore dressing 2-mineral dressing, 3- milling. In case of mineral processing one of the main aim is to regulating the size of the ore. We can define mineral processing as a process of physically separating the grains of valuable mineral from the gangue mineral, to produce an enriched portion or
