If you want to leach gold you need an oxidizing environment (add chlorine gas or clorox) until you reach an ORP of 1000mV, at a Ph of about 5, hopefully warm temperature and you will leach gold. Once in solution, separate liquid from solids, reduce the ORP to 100 -500 mV using NaHSO3 and your gold …
31-08-2016· Chlorine Volatilization of Gold Loss of gold by volatilization was recognized from time to time and was the cause of serious monetary loss in treating gold-silver ores by chloridizing roasting, but the reason for this loss seemed to be little understood.
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.
The chlorination reaction may be conducted under pressures of 1 to 2 atmospheres, absolute. In order to obtain the maximum recovery of gold from the ore, staged reactors may be used. The amount of chlorine consumed to made gold by-products is small since the amount of gold in the ore is generally small. Excess chlorine is used in the process.
Separating fine gold particles from black sands is one of the biggest challenges that gold prospectors have to deal with.

Experience has shown how difficult it is to obtain information regarding laboratory tests in connection with the gold ore chlorination process for the extraction of gold from its ores, and I therefore present the following method, somewhat in detail, for the benefit ...
Recently, the U.S. Bureau of Mines examined the recovery of gold by chlorination of refractory carbonaceous and sulfidic ores, comparing various treatment methods in which a ground ore pulp is contacted with chlorine gas and activated carbon is added to the pulp for a carbon-in-chlorine leach (CICL). The objective of this research was to demonstrate the basic feasibility of CICL technology ...

With pyritic ores a preliminary roasting to eliminate sulphur is necessary. The ore is reduced to a fine state of division and amalgamated simultaneously in a stamp-mill, the solid gold-amalgam separated from the liquid mercury by filtration through leather under pressure, and the mercury distilled.
Add the water/precipitant solution slowly to the acid. Immediately the acid will change to a muddy brown appearance as brown particles of gold form in the water. This brown "mud" is, despite its appearance, pure gold. 9. Give the precipitant about 30 minutes to do its job. 10.
This Guide is best suited for gold plated or pure gold object. THIS SHOULD ALSO NEVER BE ATTEMPTED INDOORS. *Cupellation is a refining process in metallurgy, where ores or alloyed metals are treated under high temperatures and controlled operations to separate noble metals, like gold and silver, from base metals like lead, copper, zinc, arsenic, antimony or bismuth, present in the ore.

30-09-2018· 1. Introduction. Gold has been an important metal in home and industrial application throughout the human history. The very significant properties of gold such as high melting point, strong acid resistance, good electrical conductivity, good ductility and resistance to x-ray [1,2] has made it widely useful in aerospace, electrical, electronic and various other industries [3,4].
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.
Hannay and Ballantyne, in 1887, proposed the use of liquid chlorine or chlorine compressed at more than four atmo-spheres, or chlorine evolved by electrolysis; they also aimed at overcoming the precipitation of any gold within the ore by the use of cyanide of potassium, and the subsequent precipita-tion of the gold by electrolysis.
Gold Recovery 101 Gold can be found in almost everything we see and touch; there are several important industrial uses for gold in electronics, dentistry and aerospace; however, almost 80% of gold ends up being used for jewellery. While jewellery is the end of the road for most mined gold, there are many ways it occurs in nature.
