Gold Chlorination Process

Gold Chlorination Process by Miller

08/07/2015· 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

Newbery–Vautin chlorination process Wikipedia

The process of gold extraction from ores via its absorption in chlorine gas, from which it is reduced to a metallic state, is not a very new discovery. It was first introduced by Karl Friedrich Plattneraround 1848, and at that time promised to revolutionize the processes for gold extraction. By degrees it was found that only a very clever chemist could work this process with practically perfect results, for many reasons. Lime and magnesia might be contained in the quartz, and would be attacked by the chlorine. These consum

How to Leach Gold Ore With Chlorination Sciencing

25/04/2017· Gold can be leached from stone through alkaline or acidic-based products, including halogens, such as chlorine, iodine and bromine. Halogens are reactive, non-metal elements with seven electrons in their outer shell which allow them to easily combine with other elements. The use of chlorine is both the cheapest and most plentiful method for leaching gold. When you mix sodium chloride and

Gold Chlorination Processes & Methods

In Liddell’s Handbook of Nonferrous Metallurgy, Vol. 2, 1945, there is to be found a very complete account of the uses of chlorine as applied to the recovery of gold and silver, in Chlorination Processes & Methods. Introducing the chapter entitled “Chlorine Metallurgical Processes” Liddell says: Chlorine as a metallurgical agent appears to have lost ground during recent years, and much

The Chlorination of Gold Ores.

The history of the chlorination process is interesting, and not commonly known, so that a brief account of it will not be out of place. Dr. Percy—rightly called the father of English Metallurgy —in 1848 read a paper on the value of chlorine as a means of extracting gold from ores ; in the same paper he suggested the use of hyposulphite of sodium as an after treatment for the extraction of

Miller process Wikipedia

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 before gold does, and they can then be removed as salts that are insoluble in the molten metal.

Processing, smelting and refining gold World Gold Council

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 produces gold of only about 99.5 percent purity. The
