The Miller process uses gaseous chlorine to extract impurities when gold is at melting point; impurities separate into a layer on the surface of the molten purified gold. The Miller process is rapid and simple, but it produces gold of only about percent purity. The Wohlwill process increases purity to about percent by electrolysis.
Impactchamber grain mills like the Nutrimill and Wonder Mill are best for grinding fine grades of flour but have less grinding range than burr grain mill models like the Country Living Grain Mill. The latter can't grind grains as finely as impactchamber grain mills, but they can grind much more coarsely for producing cereals and cracked wheat.

In most gold ores, the final process to extract the tiniest gold particles is the use of cyanide to dissolve the gold. Cyanide, in the presence of oxygen actually dissolves both gold and silver. It is both efficient and inexpensive, so it is widely used in precious metal ore processing.

We strive to keep gold mining and rock crushing accessible for small to medium size mining operations. Small to medium size miners know that affordable production equipment, such as jaw rock crushers, hammer mills, pulverizers, portable gold processing mills are incredibly difficult to find.
Although a very rich ore may have some visible gold present, the vast majority do not actually have any visible gold present, and only crushing and processing of the ore will release the gold within to host material. For example, lets say that a mine was processing ore valued at 1 troy ounce of gold per ton.
