Beneficiation (Metallurgy) - an overview ScienceDirect Topics
Being different from iron ores, most nonferrous metal ores are low grade, with metals in the forms of complex mixtures of sulfides, oxides, carbonates, and silicates. Therefore, to be economically extracted, nonferrous metal ores are normally concentrated by mineral beneficiation to separate the metal from waste rock prior to the extraction steps.
