A stamp mill is a mechanical device used to separate gold from rocks and ore. It features a number of sizable steel stamps. These stamps are attached to powerful battering arms, which raise and lower the stamps. When the stamps are lowered they come crashing down with a powerful force, crushing the material beneath them.

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.
Oct 28, 2016 The ore is then fed into the mortar-box of a stamp mill, where it is pulverised to the required degree of fineness. In wet crushing, a stream of water is introduced also, and the blows of the stamps splash the water and pulp against screens set in the side of the mortar, the finely-divided ore being ejected in this way.
The gold ore was crushed by hand and then washed in a box to separate the waste material. The ore was pulverized in a circular rock-lined pit by stones attached to horizontal poles fastened in a central pillar and dragged around the pit by horses this device is called an arrastra. About this time a small stamp mill
Sep 25, 2017 Sep 25, 2017 Gold veins were locked up in rock, and ores needed to be grinded up to separate out the gold.

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 ...
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.
A California stamp mill was a building housing all the basic equipment needed to crush ore and recover gold and silver. Typically set into a hillside so material could move through most stages in the process by gravity, the mill received ore on the uphill side.
