Modeling of Au Chlorination Leaching Kinetics from Copper
This study showed the kinetics of gold chlorination leaching from an anode slime complex containing copper, silver, barium, selenium, and tellurium. AgCl and BaSO4 control the rate of gold leaching, and the interface transfer and diffusion across the product was selected as the desirable kinetic model. The concentration of hydrochloric The cuprous oxide is dissolved in the metal, and so carries oxygen to all parts of the molten mass. The process is efficacious, but the gold is, of course, contaminated with the reduced copper. The use of manganese dioxide in the Transvaal in refining gold-zinc-slimes from the cyanide process was described by Johnson and Caldecott in 1902.Gold Refining Methods 911 Metallurgist

How to refine gold? Gold refining chlorination purification
Here is a detailed introduction to the gold refining chlorination purification process, take a look at it. Gold refining chlorination purification process: High purity gold processing process: Acceptance of alloy gold → pulverization → sodium chlorate sub-gold → sodium sulfite reduction → sprinkling beads machine sprinkling beads →Saganoseki Smelter and Refinery started operation of its copper anode slimes treatment plant using a hydrometallurgical process—the first of its kind in Japan—in 1997 (Toraiwa et al.

Precious Metal Refining 911 Metallurgist
Precious Metal Refining. Precious Metal Refining: Dore is a mixture of gold and silver typically containing less than 5% base metal impurities. The exact composition varies widely depending on its source and processing history. Dore producers, in deciding whether or not to refine their dore, can custom design a facility around a single feedstock.The obtained linear model is significant for the response of gold ion concentration in the electrolyte. According to the probability of insufficiency, the model is thoroughly able to describe the changes in the response variable. The obtained model is presented in Eq. (15): (15)R = -184.83 + 345.81A + 13.63B + 85.3C.Optimization of the operating parameters in gold electro-refining

A Review of the Cyanidation Treatment of Copper
Globally, copper, silver, and gold orebody grades have been dropping, and the mineralogy surrounding them has become more diversified and complex. The cyanidation process for gold production has In the Miller process, gold is refined by chlorine. Chlorine and silver combine with base metals to form chlorides, while gold is left untouched by this. Doré bars are melted in a furnace and then chlorine is added to form chlorides. After a few hours, the chlorides are removed from the heat and skimmed away, leaving just the gold, which canTypes of Gold Refining Sciencing

Gold Chlorination Process by Miller 911 Metallurgist
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.
