2021-8-23  The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore from the gangue particles. Ore found in the earth contains many impurities like sand, grit, rocks etc. which are collectedly known as “ Gangue ”. The concentration of ore
