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.

Stamp Mill Crisson Gold Mine

This Stamp Mill dates back to the 1800’s. It has been used at several mines in the Dahlonega area as well as in other states. It was placed on the site in the 1960’s. This Stamp Mill has ten stamps with each one weighing 450 lbs. each. The purpose of the Stamp Mill is to crush gold bearing rock into sand so that it can be processed.

Stamp Mill Digital Desert

A stamp mill was a mechanical crusher, noisy, heavy and somewhat awkward to operate. The stamps were heavy metal weights that were lifted and dropped on the ore by a crankshaft. The crushed ore would then be further refined, usually by a mercury or cyanide process. The miner would bring the ore to the mill and load it into the ore car.
