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.

Gold Chlorination Process by Miller

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

History Trilogy Refinery

Chlorine was first used to recover gold from residues from amalgamation. Later, in the 1880’s Chlorination was used in big mining operations in the American and Australian gold fields. At the present time unfortunately chlorination for gold recovery is used on extremely small scale where gold is a minor constituent with other precious metals.

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

Gold refining by solvent extraction—the Minataur™ Process

refining of gold from various feed materials. During the past year, two pilot-plant campaigns were carried out in which 5 kg/d of high-purity gold was produced from silver-refining anode slime and from gold-electrowinning cathode sludge. Following the success of these trials, the first full-scale gold refinery to use this process has recently been

How to Refine Gold: 2 Major Techniques of Gold Refining

Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

Gold processing Britannica

Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms

Calcination Wikipedia

Calcination refers to heating a solid to high temperatures in absence of air or oxygen, generally for the purpose of removing impurities or volatile substances. However, calcination is also used to mean a thermal treatment process in the absence or limited supply of air or oxygen applied to ores and other solid materials to bring about a thermal decomposition.
