  • 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 ().There are many different types of beneficiation, with each step furthering the concentration of the original ore.
