Gold Extraction

The increase in gold extraction can be attributed to increases in residual Cu (II) in solution with increasing pH value resulting from the increase in free NH 3 ( Senanayake, 2004a,b ). Leaching at a higher pH value can also be beneficial in improving silver extraction and stabilizing silver in solution.

Gold processing

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 ...

Gold processing | Britannica

 · The best-known of the exogenetic ores is alluvial gold. Alluvial gold refers to gold found in riverbeds, streambeds, and floodplains. It is invariably elemental gold and usually made up of very fine particles. Alluvial gold deposits are formed through the weathering actions of wind, rain, and temperature change on rocks containing gold.

Summary of Gold Extraction Process

The flotation gold extraction process is also used to process polymetallic gold-bearing ores such as gold-copper, gold-lead, gold-bismuth, and gold-copper-lead-zinc-sulfur ore. For this type of ore, the flotation process can effectively identify and extract various gold-bearing sulfide concentrates, which is conducive to the comprehensive recovery of mineral resources.
