Processing, smelting and refining gold World Gold

2021-5-13  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

Miller Process. The “Miller Process,” also known as pyrometallurgical chlorination, is when chlorine gas is pumped into molten bullion. Base metals react with the chlorine to form chlorides, which either evaporate or rise to the surface to form a slag.

2009-8-27  reversal of the adsorption process with most of the gold desorbing from the carbon back into solution. This produces a small volume of solution with a high gold concentration. The gold is recovered from this solution by electrowinning, zinc precipitation or refining technology such as the Mintek Minataur process.

Extraction of Gold

The process is applicable directly to gold- bearing sand, and to gold-bearing rocks after crushing. The crushing is effected by stone-crushers, rolling-mills, and stamp-mills. The washing is carried out either by subjecting the material to the prolonged action of flowing water, or by mechanical agitation with water in deep iron pans or " cradles."

2020-8-18  By 2000 bc the process of purifying gold-silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold
