The Miller process is an industrialscale chemical procedure used to refine gold to a high degree of purity 99.5. 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

The impure Read More

Miller Gold Refining Process by Chlorination

In order to purify gold and remove the silver from it by any process analogous to the cementation with nitre or salt in a reasonable time, the alloy must be in such a fine state of division that the silver will be removed almost instantly, or diffusion must be assisted by actually keeping the alloy in a molten state. Nitric acid, the active ingredient in the first cementation process described
