Ore Concentration Method

Some of the common methods of ore concentration are discussed below. 1. Gravity separation or Hydraulic wash. In this method, the ore having high specific gravity is separated from the gangue that has low specific gravity by simply washing with running water. Ore is crushed to a finely powdered form and treated with rapidly flowing current of water. During this process the lighter gangue particles are
