The mill could process up to 2,850 tons per day. The process flowsheet incorporated a carbon in leach (CIL) circuit for gold and silver extraction, followed by zinc cementation of the precious metals and smelting of a doré product. Reported recoveries were 91% for gold and 45% for silver.
Stamp Mill Geology Gold Mines Desert Mining History Stamp Mill 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 of treating gold ore to extract gold (and silver) and, therefore, produce bullion is called milling. The building housing the process is called a mill. The finely pulverized material that is rejected from the mill after the gold has been extracted is called tailings.
In modern times though, mining for gold is a much more intensive, yet sophisticated process. Most surface, or alluvial gold has been found, which is why gold is mainly mined from the earth today. It's largely a matter of technology and requires much expertise and elaborate equipment. Mining for gold today can essentially be broken down into 9 ...
