Stamp mills were effective machines for mining gold in the early years, even with the challenges associated with using them, they acted as the force that propelled gold mining into commercialization. Millions of ounces of gold have been recovered as a result of this ingenious tool.
A stamp mill is designed to crush rock. In Idaho, granite and porphyry rocks would be crushed to expose any gold contained within. The crushed rocks would then be panned or sluiced to separate the gold from the rock material. Stamp mills can come in various sizes and complexity, from manually powered stamps to large steam powered machines.

The stamp battery is the heart of a stamp mill and the mechanical separation process to break the various components of the ore apart, freeing the gold from its enclosing material. To start, the mined rock enters the mill and passes over a grizzly (like a grate- kit# M1 ) that has bars spaced to allow rocks that the stamp battery can handle to ...
Metal stamps crush the ore. A worker spreads more mercury on the copper plates. After a few days, the free gold bonds to the cyanide solution. The gold/cyanide mixture called the pregnant solution is mixed with zinc shavings. The zinc-shavings separate the gold from the solution. Build the stamp mill on a hill.
