Hard Rock Mining Gold and Silver Ore and processing it

This bin allows the mill to take in ore at a constant feed rate. Various crushing systems are used, usually starting with a coarse crushing with something like a jaw or cones crusher, followed by a fine crushing using something like a ball or Rod mill. After crushing, the extraction processes vary greatly, depending on the metal or mineral to be extracted. However, since we are focusing on ...

How Miners Lived, Dressed, and Died in the 1800s

 · In many ways, the miners who went to work underground in Nevada and elsewhere in the late1800s were guinea pigs. Square set timbering, the practice of building perfect cubes to account for the sporadic pockets of ore unique to the Comstock Lode, solved the deadly caveins that had been endemic to site, but only after countless lives had been lost.

Mineral Processing

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.

Nevada Mining History

Nevada has experienced a modern gold mining boom, starting with the discovery of the Carlin Trend gold deposits in the early 1960's. First, open pit mines opened to tap the new ore discoveries. In recent years many mines have gone underground to produce gold from deeper ore bodies.
