Crushing, Grinding and Concentration of the Ore

(1) Crushing and Grinding of the Ore. The ores occur in nature as huge lumps. They are broken to small pieces with the help of crushers or grinders. These pieces are then reduced to fine powder with the help of a ball mill or stamp mill. This process is called pulverisation. (2) Concentration of Ore or Ore Benefaction
