29-02-2022 · (i) Dressing of the ore is an essential process in the extraction of metal from its ore. Answer: 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.

Beneficiation of Iron Ores – IspatGuru

03-04-2022 · 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.

Concentration of Ores: Hydraulic Washing, Froth Flotation

Concentration of Ores. An ore of a metal is an impure source, this means other than the metal it consists of many other impurities such as sand, grit, clay, rocks etc. These impurities are collectively known as gangue. Gangue is generally commercial valueless and we must separate it from the ore. This entire process is the concentration of ores
