The Miller process is an industrial-scale 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 ...

Gold Refining. Gold mines process ore using various techniques to produce an alloy composed primarily of gold and silver, which is called a dore bar. The composition of dore can vary significantly between mines, but generally the gold dore bars the Perth Mint processes are composed of between 70-80% gold and 10-15% silver.

Describes the Miller Chlorination Process used in gold refining in all its steps and chemistry. The reactor and chemical used to obtain pure 99.999% gold bars.
Miller's Gold Chlorination process was introduced by F.B. Miller. The refining process employs chlorine gas, which passed into molten gold covered with a layer of borax and silica, and reacts with most of metals present in the molten charge. Platinum group metals do not react. Basically, gold is slightly attacked in the first moments and all the chlorides formed rise to the surface and are ...

The principle and equipment for gold electrolysis. Gold electrolysis was invented by Emil Wholwill in 1874. But various versions of this process have been developed over the years. It is an electrochemical process which has been applied in many large-scale gold-refining establishments or industries.
An overview on how to refine precious metals. There are many kinds of materials that yield pure gold, platinum, or silver when refined. Though it's usually a little intimidating the first time you do anything, refining precious metals yourself is relatively easy to do (even with no experience) provided you have the right information, supplies, and equipment.
