MILLING. Following removal of the native copper from the ore through the gravity circuit, or when non-native copper ore by-passes this circuit, the ore continues to the gravity thickener and the thickened ore then feeds through to the ball mill.
From an accessory to gravity methods, flotation very rapidly became a major process and finally, from 1923 to 1927, all but eliminated the gravity method in the treatment of low-grade sulfide copper ores. The rapid development of ball-mill grinding must also be attributed to the adoption of the flotation process, since it was the incentive for ...

A stamp mill consists of a set of heavy steel (iron-shod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.As the cam moves from under the stamp, the stamp falls onto the ore below, crushing the rock, and the lifting process is repeated at the next pass of the cam.
