Concentration of ores - Metallurgy | Chemistry

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 ...

Concentration of Ores: Hydraulic Washing, Froth Flotation ...

In this method of Magnetic Separation, we use the magnetic properties of certain metals to divide them from the non-magnetic gangue. Here we place the powdered ore on a roller belt. One belt of this roller is a magnet. So the magnetic material attracts to the metal belt and stays on the belt. The non-magnetic gangue falls in a heap from the belt.
