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

Newbery–Vautin chlorination process Wikipedia

OverviewDescriptionBackground

Claude Theodore James Vautin, a man of much practical experience of gold mining and extraction in Queensland, Australia, together with James Cosmo Newbery, analytical chemist to the government of Victoria, have developed a process which they claim to combine all the advantages of the foregoing methods, and by the addition of certain improvements in the machinery and mode of treatment to overcome the difficulties which have hitherto prevented the general adoption of the chlorination process.

Chlorination an overview ScienceDirect Topics

Chlorination leaching is used in PGM refineries around the world. Table 29.2 summarizes the feed materials, chlorination conditions, and gold recovery methods and efficiencies within the refinery processes (adapted from information provided in Crundwell et al., 2011).The feedstocks are high-value, low-volume materials often derived from base metal refineries, typically containing ∼25% Pt

Processing, smelting and refining gold World Gold Council

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 Wohlwill process increases purity to about 99.99 percent by electrolysis.

Gold cyanidation Wikipedia

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.. Production of reagents for mineral processing to recover gold, copper, zinc and silver represents

Gold refining by solvent extraction—the Minataur™ Process

feed material was leached in 6 M HCl, with chlorine contin-uously sparged into the leach reactor. After leaching, the solid residue was filtered from the gold-containing solution. A summary of the pilot-plant leaching results is shown in Table II. Because of its high gold content, the Peñoles feed material yielded very little residue.

How to Use Bleach on Gold Ore to Remove Gold Sciencing

Gold is an almost non-reactive metal, but halogens — chlorine, bromine, fluorine and iodine — can dissolve it. Chlorine is the cheapest and lightest product that can achieve this. Bleach is the chemical compound sodium hypochlorite. When combined with hydrochloric acid, the mixture produces chlorine that dissolves gold from gold ore.
