Beneficiation - Wikipedia
In the mining industry or extractive metallurgy, beneficiation is any process that improves (benefits) the economic value of the ore by removing the gangue minerals, which results in a higher grade product (concentrate) and a waste stream (tailings). Examples of beneficiation processes include froth flotation and gravity separation. Other economic uses of the term are in use. For example, in the diamond industry, the beneficiation imp…
