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 (ore concentrate) and a waste stream (tailings). there are many different types of beneficiation, with each step furthering the concentration of the original ore. · text under ccbysa licensexinyang minerals groupthe xinyang minerals group,approved by the ministry of foreign trade economic cooperation, is a comprehensive enterprise group that specializes in mine opening, mineral processing, flame retardant powder production,environmental pollution treatment,mineral fertilizer production, import export trade, scientific research and owns hundreds of innovation patents.
