• process gold ore mill

Operations

Ore is treated using a two-stage crushing process, followed by a two-stage grinding circuit that consists of a semi-autogenous grinding mill and a ball mill. Most of the ground ore is fed to a gravity circuit that recovers about two-thirds of the gold,

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 miner would bring the ore to the mill and load it into the ore car.

Smelting and Roasting Ores to recover gold, silver and other metals

The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.

Agitation Leaching Theory and Practice

Ore that contains free gold may not yield a sufficiently high recovery by sole use of cyanide leaching, due to a very long dissolution time for large gold particles. Such ore may first be subject to a gravity recovery process to recover the free gold before being
