In the mining industry or extractive metallurgy, beneficiation is any process that improves the economic value of the ore by removing the gangue minerals, which results in a higher grade product and a waste stream (tailings).
A process where ore is soluble and impurities are insoluble, widely used extractive metallurgy technique which converts metals into soluble salts in aqueous media. Leaching is easier to perform and much less harmful, because no gaseous pollution occurs.
Refining consists of purifying an impure metal. It is to be distinguished from other processes such as smelting and calcining in that those two involve a chemical change to the raw material, whereas in refining, the final material is usually identical chemically to the original one.
Tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction of an ore. Tailings are distinct from overburden, which is the waste rock or other material that overlies an ore and is displaced during mining without being processed.
