Miller process ore refining Britannica

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.

Processing, smelting and refining gold World Gold

2 天前  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 ...

2005-1-1  The Miller process can produce marketable 9950 grade gold and meets the majority of the above-mentioned criteria. However, the subsequent process of electrorefining to refine 9950 grade gold to 9999 grade does not meet all the criteria and has therefore been carefully reviewed and investigated over the past 5 years.

Gold refining by solvent extraction—the Minataur™ Process

2009-8-26  The Minataur™ Process has been evaluated in two pilot-plant campaigns treating 5 kg of gold per day. The first campaign, at Met-Mex Peñoles silver refinery in Torreon, Mexico, operated continuously for three weeks using conditions appropriate to the production of 99.999% gold. The feed to the process was gold-containing anode slime from the silver Gold refining by solvent extraction—the Minataur™ Process
