The procedure of ore concentration is a critical stage in obtaining pure metal from ore. Separating ore from gangue particles is required for metal extraction. Ore discovered in the soil contains several impurities such as sand, grit, pebbles, and so on, which are collectively referred to as "Gangue.". The initial step in metal extraction ...

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 refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
