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 ...

Gold, as it occurs in Nature, is never pure. Occasionally the amount of alloying metal is less than 1%, hut as a general rule it is greater; the commonest alloy, in fact, the invariable one, being composed of gold and silver.
An expansive resource for new and used machinery for industrial, jewelry and precious metal manufacturing.
Dec 05, 2019· The Miller process is a gold refining process that produces gold of approximately % purity, sufficient for many applications. It is faster and less costly than other refining options used to produce purer gold, which makes it a popular choice at some refineries.
The Miller process is an industrialscale chemical procedure used to refine gold to a high degree of purity (%). 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.
Miller''s Gold Chlorination process was introduced by 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 .

The two gold refining methods most commonly employed to derive pure gold are: the Miller process and the Wohlwill process. 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 ...
