Page ID. Beneficiation is any process which removes the gangue minerals from ore to produce a higher grade product, and a waste stream. Beneficiation may involve physical or chemical processes. Often, as in the case of panning for gold, the desired ore or metal is denser than the gangue. The latter can be suspended in a stream of water and ...

The benefits of mineral beneficiation or ore dressing are as follows: High volume production in lesser time. Increases the metal content of the ore. Decreases the gangue content to get the most out of the ore. It provides raw materials that support the country's infrastructure and economy.

Mineral sands are mined by surface mining methods including open cut mining, suction dredging, and hydraulic mining. The first stage of the mining process is to remove all timber and topsoil from the mine site. The topsoil is stockpiled for later rehabilitation of the site after mining has been completed. 5.3.1.1.
