- Copper Ore Flotation Process Plant
by flotation Measurement made easy — Introduction The flotation process can separate a required mineral such as copper, nickel, molybdenum or zinc from ore. Flotation can separate this mineral from waste materials or from another mineral. The process starts with crushed ore. A ball mill receives the crushed ore and reduces its particle

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.
