Feb 12, 2016· Simply put, the trick to refining gold is to dissolve impure gold in acid such that all the impurities fall out, and then to pull the pure gold back out of your acid solution. Practically, the...
With Millers process of refining impure gold with chlorine gas patented in Britain in 1867 and Emil Wohlwills electrorefining process introduced in Hamburg, Ger., in 1878, it became possible routinely to achieve higher purities than had been allowed by fire refining. Ores. Inquire Now; Gold Refining TechniquesSciencing Process.
Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
