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 A stamp mill is similar to a mortar and pestle. Indeed, the vessel holding the ore being crushed is called a mortar. A stamp mill works by repeatedly dropping one or more heavy stamps on ore in the mortar.
