From its found to the next 80 years, miners blasted and carted out some $17 million in gold and silver. The Nevada Mill was erected on the site in 1887 to process the vast amounts of ore taken out of the Chollar Mine.
While stamp mills throughout the west were similar in how they crushed the ore, the second stage – separation of the metals from the crushed ore – varied widely based on an array of factors. Basic ores, sometimes called "free milling ore", could be separated by relatively simple processes like amalgamation.
Gold mining is the extraction of gold resources by mining.Historically, mining gold from alluvial deposits used manual separation processes, such as gold panning.However, with the expansion of gold mining to ores that are not on the surface, has led to more complex extraction processes such as pit mining and gold cyanidation.In the 20th and 21st centuries, most volume of mining …
The ore undergoes primary crushing at the mine, before being delivered by ore passes to the mill complex for further crushing, grinding and flotation. Grasberg's milling and concentrating complex is the largest in the world, with four crushers and two giant semi-autogenous grinding (SAG) units processing a daily average of 240,000t of ore.

The Chilean mill was a machine used on gold fields in an early period of gold mining.The machine was composed of two rotating wheels that would revolve over a pan filled with gold-bearing rocks. The idea was that the wheels would break open the rocks with gold, so they could harvest gold from multiple rocks at a time.
The Chilian mill is a series of heavy, upright, cast-iron wheels, which run in a circular groove, or trough of cast-iron, and this groove has sieves, somewhat similar to the stamping box, for the escape of rock, when sufficiently pulverized.
