Miller Gold Refining Process by Chlorination

24/03/2016  Since one inch of gold will balance a column of about 19 inches of water, the liquid in this tube must be from 10 to 11 feet in height to force chlorine through the 7 inches of gold in the pots. The pressure exerted is about 5lb. per square inch. A four-way tube of lead or pottery is pressed through the second neck of the vessel, and each arm is connected by thick rubber to glass stopcocks to which ½

Gold refining by solvent extraction—the Minataur™ Process

for the chemical refining of gold from chloride media has shown considerable promise for the selective extraction of gold from silver, platinum-group metals (PGMs), and base metals, and has potential applications in the refining of gold from various feed materials. During the past year, two pilot-plant campaigns were carried out in which 5 kg/d of

Processing, smelting and refining gold World Gold

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. The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity.

Gold processing Britannica

With E.B. Miller’s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill’s electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.

Gold Chat: The Gold Value Chain Part II - Refining

24/06/2008  With purity, 99.5% purity gold can be produced using a chlorination process (impure gold is melted and gaseous chlorine is blown through it with the impurities joining with the chlorine). It is rapid and simple and therefore cheap but only goes up to 99.5%. To get to 99.99% you need an electrolytic process (stick impure gold into a solution of hydrochloric acid and gold chloride, pass an ...

Gold parting - Wikipedia

It is an electrolytic process using pure gold for the cathode (or titanium as a starter cathode) and chloroauric acid (gold chloride-hydrochloric acid) as the electrolyte; this is made by dissolving gold with chlorine gas in the presence of hydrochloric acid. Gold is dissolved at the anode, and pure gold, traveling through the acid by ion transfer, is plated onto the cathode. Silver forms an insoluble chloride slime
