Treating ore by milling is generally a two-step process, first the ore must be crushed, then the crushed ore must be treated to separate the valuable mineral content from the waste rock. Elaborate milling operations at …

The world's gold production has changed over the past 30 years. The exploration and discovery of large, free-milling gold deposits in major mining districts has declined. Mining companies face a difficult decision. Do they process large, low-grade deposits or look for smaller, often more complex ones in remote, often hard-to-reach locations?

The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In …

The gold milling process consisted of three general steps: (1) Sorting the ore by size. (2) Crushing the rock. (3) Extracting the gold. The rock fragments were sorted according to size in a grizzly, which was device consisting of a series of spaced bars, rails, or pipes, above a forward moving conveyer belt to a crusher machine.
