Rodman Paul believed stampmill technology arrived in the Far West by way of the American South, where it was in place in Georgia, Carolina, and Tennessee by the 1830s and 1840s. ... curse for the millman who depended on gravity separation to treat gold and silver ores. The finer the grind the more likely the prospect of "sliming" the ore and ...
Description; A stamp mill consists of a set of heavy steel (ironshod wood in some cases) stamps, loosely held vertically in a frame, in which the stamps can slide up and down. They are lifted by cams on a horizontal rotating shaft.
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 process explained: The miner would bring the ore to the mill and load it ...

With the introduction of the cyanide process, other methods became obsolete. Mill workers mixed goldbearing ore with a percent by weight sodium cyanide solution and agitated the mixture in the presence of air, dissolving the gold. Next, a vacuum chamber removed the air. Powdered zinc added to the mixture returned the gold to a solid.
