Effect of Silver on Chlorination Bromination of Gold

2017-02-11  Curve III shows that the extraction of gold from an alloy of gold 9 parts and silver 1 part by means of chlorine is but little affected by the presence of 10 per cent, of silver; that this is still less the case with bromine can be inferred from the bromination curves in Fig. 3, where pure gold and gold with 20 per cent, of silver are connected by straight lines.

Chlorine extraction of gold - DUNN; WENDELL E.

The gold compounds and other metal chlorides form a salt melt from which the gold is separated. The yield of gold is almost 100% of the gold present in the ore. The process can be conducted continuously by continuously adding roasted ore to a fluidized bed of the ore which is subjected to chlorine and continuously removing a portion of the bed.

Extraction of Gold

The so-called " brown gold " is formed by the action of nitric acid on an alloy of gold and silver containing 20 per cent, of gold. The silver dissolves, leaving the gold as a brown, spongy sheet, reconverted at 1040° C. into ordinary gold. The brown form (β) differs from ordinary (α) gold in density and magnetic properties.

Gold processing - Refining Britannica

Refining. Gold extracted by amalgamation or cyanidation contains a variety of impurities, including zinc, copper, silver, and iron. Two methods are commonly employed for purification: the Miller process and the Wohlwill process. The Miller process is based on the fact that virtually all the impurities present in gold combine with gaseous chlorine more readily than gold does at temperatures ...
