Concentration of Ore: Definition, Classification, Methods
Definition of Concentration of Ore. Ore concentration is the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals in their pure form. In other words, it is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use.

Concentration of Ores
Explanation: Electrostatic separation is a method used for concentration or separation of ores when they are good conductors of electricity. It is based on the principle that when an electrostatic field is applied the ore particles, which conduct electricity, get charged and get repelled by electrodes having same charge and all thrown away.
