Introduction of Mercury-Free Gold Extraction to Small
The gold-bearing quartz veins are crushed into very coarse gravel and then ground into dry powder in a ball mill without adding water. The milled ore is subsequently washed down a chute covered with a piece of cloth. The gold yield from the amalgamation method is strongly dependent on processing techniques such as sluicing. The advantage of

Estimation of Mercury Losses and Gold Production by
Gold is extracted by amalgamation of concentrates or the whole ore, and the amalgam, usually with 40–50% mercury, is heated. By heating, mercury is evaporated leaving behind the precious metals . When miners amalgamate the whole ore in small ball mills, the mercury loss can be as high as 15 parts of mercury per part of gold produced .

Winning the Metal: Ore Mills of the West – Western Mining
By the 1930s, many stamp mills were retrofitted with ball crushers, replacing the stamps that were originally used. 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.
