Chilean mill - Wikipedia

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. One of the earliest such machines was built in Ballarat in Victoria, Australia during the Victorian gold rusha

Restoring Historical Mining Equipment: (52)

Chilean Mills evolved over the years as technology improved and mining techniques advanced. There were at least two major changes to the later Chilean Mills. The first was to use cast iron wheels in place of granite and the process would go from a batch process to a feed and bleed process. The early mills would process the ore in batches.

Gold processing 101 - Mining Magazine

An ore containing 1% sulphur will produce a mass pull of approximately 5% by weight to a bulk flotation concentrate where recovery is the key driver. If this ore also contains 1g/t Au (for GSR =1), and 90% recovery to concentrate is achieved, then 0.90g will be recovered and with a concentration ratio of 20 (5% to concentrate) this corresponds to 18g/t Au in concentrate.
