  • What is Concentration of Ore? Definition, Physical

    The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc from the ore to extract the metals In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use The ore can be concentrated or separated by both

    Therefore, these mines crush and grind the ore, then use gravitational and magnetic concentration methods to produce concentrates with an iron content of about 65% Depending on grain size, the concentrate is then shipped as is, or agglomerated into balls about a centimetre in diameter and fired to produce hard iron ore pellets Steel companies take the pellets and coke made from coal and load
