  • What is the Beneficiation Process? Mining Information

    Oct 01, 2014 · Size classification will require screening, de-sliming and cycloning. In the case of a lower-grade iron ore, the beneficiation process includes activities such as crushing, milling, gravity or heavy media separation, screening and silica froth flotation. These activities will help improve the concentration of the ore and remove impurities.
