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.

mining during the 1900s. The discovery of rich silver ores at Tonopah in 1900 and rich gold ores at Goldfield in 1902 stimulated great activity in mining exploration throughout Nevada. Many placers discovered during the 1906-10 period were found by men looking for ores similar to ores at Tonopah and Goldfield.
Mar 23, 2021 Due to their significantly higher grades, refractory ores yield costs per ounce that are frequently lower than the average costs for conventional ores. Mill-head grades of refractory deposits can be 86 percent higher as a consequence, the operational costs per ounce of gold produced are approximately 19 percent lower in the case of refractory ...
A gold mill houses the equipment necessary to remove gold from the surrounding waste rock, either by concentrating it or by mechanically separating it.

The Mill recovered metals from the ore by gravity separation and by selective flotation. Sulfide ore minerals were concentrated by froth flotation, a method used in the early twentieth century that allowed processing of ores. The original mill equipment is still in working order. It is the only intact and functional mill of its kind in Colorado.
