    18.2.2 Concentration or Dressing of the Ore Generally the ores are found mixed with earthy impurities like sand clay lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores.

    Apr 03 2014 · Iron ore is a mineral which is used after extraction and processing for the production of iron and steel. The main ores of iron usually contain Fe2O3 (70 iron hematite) or Fe3O4 (72 iron. magnetite). Ores are normally associated with unwanted gangue material. Grade of iron ore is usually determined by the total Fe content in the ore.
