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

10/09/2016· 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. They would feed amounts of ore into the

Chilean Mill Mineral Processing & Metallurgy
The Quartz Mill AKA Chilean Mill is one of the more popular types of the original Chilean mill. Still used for certain grinding problems, this mill employs the convex-concave principle of crushing ores, resulting in a product surprisingly low in slime content and which has its particles, such as sulfides and gold, well polished and free of recovery retarding tarnish. The Chilean Mill consists
