The purpose of the froth floatation is to separate the 0.5% of copper from the 99.5% of “crud”. There are two different types of minerals in the ore at this point; the chalcopyrite is a sulphide, and the rest are silicates containing anions made from silicon and oxygen atoms. In this process, a “collector” is added to a water/mineral...
