May 23, 2015· Instructions Weigh your gold smelt. For every ounce of gold, you will need a container with a 300milliliter capacity. So, if you''re refining 5 ounces of gold, you will need a 1500milliliter container or about 1 ½ quarts. Add 30 milliliters of nitric acid for every ounce of gold. So, if you''re refining 5 ounces of gol
Gold refining by solvent extraction—the Minataur™ Process by A. Feather*, Sole*, and Bryson* Synopsis The Minataur™ Process (Mintek Alternative Technology for Au Refining) is a novel route for the production of highpurity gold using solvent extraction. Following the successful
Miller''s Gold Chlorination process was introduced by 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 ...

The procedure is very similar to refining gold in aqua regia, but the precipitant used will be different. There are several standard precipitants, different precipitants for different platinum group metals. Refining by this method is tricky and the purity of the resultant platinum group metal is often below normal standards.

chlorination gold recovery. Recovery of Gold from Incinerated Sewage Sludge Ash . In a series of studies into the development of an efficient and selective recovery process for gold that eliminates the need for water, the release behavior of gold from an incinerated sewage sludge ash heated to between 100 and 1000 C under a chlorine gas stream was investigated.
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.
