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.
The Mill has extensively been upgraded and modified including installation of a gravity jig separation system that allows the Mill to separate free gold from mill feed, as well as a tabling system that allows the Mill to further separate fine gold from gold concentrate after floatation.
