Stamp Mills for Processing Gold Silver Copper Ore

Stamps are built heavy, made from steel or cast iron heavy enough to pulverize the ore beneath. The stamps are repeatedly raised and dropped onto ore that is fed into the mill, until the coarse ore is reduced to finer material capable of further processing. The stamp mill provided an invaluable need for the early gold miners.
