Processing less waste and low-grade materials results in a reduction in the use of water, which can reduce water supply costs or operating costs of a desalination plant and the filtering of water at the end of the process. It also reduces the amount of water that ends up in a tailings dam. Grinding and crushing of ore is energy intensive and ...

Difference between Ore and Minerals. Minerals are naturally occurring substances of metals present in the earth's crust called minerals. For eg - Clay is a mineral of Aluminium. Ores are those minerals that can be used for the extraction of metal easily and profitably. For eg - Bauxite is an ore of Aluminium.

Crushing and grinding are carried out to break down the ore into smaller pieces, which increases the surface area and exposes the copper minerals for subsequent processing. Froth Flotation : Froth flotation is a common method used to separate copper minerals from the gangue (waste rock) and other minerals in the ore.
