Miller process amount of gold in the form of chloroauric acid which the Wohlwill process permanently requires for the electrolyte. Miller process The Miller process is an industrial-scale chemical procedure used to refine gold to a high degree of purity (99.95%). It was invented by Francis Bowyer Miller ( patented 1867). This chemical process involves blowing a stream of pure chlorine gas over and through a crucible filled with molten, but impure, gold. This process purifies the gold because nearly all other elements will form chlorides before gold does, and they can then be removed as salts that are insoluble in the
Commodity value Commodity value In the field of economics, the commodity value of a good is its free market intrinsic value under optimal use conditions. In a free market, the commodity value of a good will be reflected by its price. For example, if an acre of land can yield a net of 100 dollars loss by lying fallow, 50 dollars gain by being planted with corn, and 100 dollars gain by being planted with wheat, then that acre's commodity value is 100 dollars; the farmer is assumed to put his land to best use. The price of a commodity fluctuates around
