GEOLOGY

Detailed explanation-1: -Once the ore is transported to the surface of the mine, haulers feed the crushers with tonnes of large rocks, the first step in mineral processing. After they are crushed to about 15 cm (6 in) in diameter, conveyor belts route the materials into stockpiles near the concentrator building for grinding.

Detailed explanation-2: -Mineral processing can involve four general types of unit operation: comminution – particle size reduction; sizing – separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering – solid/liquid separation.

Detailed explanation-3: -Sampling is the removal from a given lot of material a portion that is representative of the whole yet of convenient size for analysis. It is done either by hand or by machine.

Detailed explanation-4: -Beneficiation includes crushing, grinding, gravity concentration and flotation concentration. Beneficiation is followed by processing activities such as smelting and refining. The beneficiation process begins with milling, which is followed by flotation for further beneficiation.

Detailed explanation-5: -Once the ores are removed from the earth, they are processed mechanically – crushed, sorted, ground, screened, decanted, filtered, and dried –before undergoing a metallurgical process to refine them into the final product.
