Stamp Mills for Processing Gold Silver Copper Ore

A stamp mill is a large mechanical device used to crush ore and extract the desired metals from the host material. It uses heavy steel stamps to crush and break apart material, releasing the valuable gold from worthless rock, allowing for the extraction of gold for further refining. The basic design of a stamp mill has been used for thousands
