Occurrence of Metals

Mar 20, 2019The processes involved in the extraction of metal from their ores and refining is called metallurgy. The three steps of metallurgy are: 1)Concentration of ore. 2)Conversion of ore into metal. 3)Refining of impure metal.

Ore Mineral

Iron ore minerals, particularly hematite and goethite, are beneficiated by a combination of size fraction, preconcentration, and flotation in stages (Fig. 13.45).Iron ore requires removal of silicate impurities of a finer size by flotation for higher-grade products of +60% Fe.
