Get PriceJan 01, 2016 Gold is a significant byproduct of the base-metals industries. This chapter focuses in particular on the practice of recovering gold from the copper industry (anodic slimes), the nickel industry, the PGM refineries, as well as within lead and zinc smelters. Recovery of gold from electronic scrap and other industrial wastes is increasingly
Get PriceThe leaching rate of gold is 86.5%, the leaching rate of silver is 48%. The general recovery rate of gold processing and melting is 80.4%. The general recovery rate of silver processing and melting is 38.2%. The value of tailings is brought into full play, and also brings efficiency to the processing plant. 2
Get PriceJan 01, 2016 The pilot-plant trials demonstrated that copper cyanide and free cyanide could be extracted from gold plant tailings producing low barren solution values ( 10 ppm), in a continuous process that produced concentrated cyanide solution for recycling to leach (∼100 g/L NaCN equivalent) and ∼99.9% copper cathodes as

Get Priceprocessing for copper removal and cyanide recovery is used. In 2015, a flotation plant was added to treat the tailings from the agitation leach plant before the tails are sent to the tailings dam. This plant produces a copper sulphide flotation concentrate and also recovers some of the residual gold and silver in the tailings. Since February 2017, due to lower grades of gold and higher copper in the feed ore, the decision was taken
