Then the finely ground rock was fed into the mill, generally by a gravity feed directly from the stamp mill. Then the rock was mixed with other minerals to separate the gold from the rest of the rock (see Ore Processing). Waste from the ore processing was generally in the form of a water slurry of finely powdered rock.
