The ore concentration is defined as the chemical process of eliminating impurities like sand, rocks, silt, grit etc. from the ore to extract the metals. In simple words, the concentration of ore is the method of separating ore from the gangue, as the gangue or matrix particles are the valueless substances that are of no use.

Chalcopyrite is a Copper iron sulfide mineral that was first found in 1725 by J.F Henckel. It was named from the Greek word for "Copper" and "Brass", and can most notably be seen as shades of yellow, green and grey. When Chalcopyrite is exposed to acid, its color palette changes to deep purple, blues, violets, and yellows.
