Abstract

At present, Cyanidation is still undoubtedly the most important and widespread of the various hydrometallurgical technologies that were used in the extraction of gold and silver from primary ores and concentrates, Metallic zinc has long been known as being a good precipitant for precious metals from cyanide solution. The technology of recovering silver from the cyanide solution by zinc shavings precipitation was studied in this paper. Experimental studies were carried out on the solution of silver cyanide, which contain 20.42mg/L of silver and 277.9mg/L of copper. The proposed procedure derived from this study is based on the dosage of zinc shavings 0.5g, soaking for 10 minutes in lead nitrate solution, a low temperature drying method for zinc shavings, and a replacement time of 10 minutes with pregnant solution, the replacement rate of Silver was 91.35%.
