【 摘 要 】

This paper studies the possibility ofextracting gold by electrochemical leaching through the use of a sodiumthiosulfate solution. In this regard, the requirements for environmentallysound technologies play a huge and vital role. Low extraction ratios and metallosses increase the cost of this process significantly and therefore it is necessaryto reduce or prevent these disadvantages. Dissolution of gold at variouselectrolyte concentrations has been studied. The influence of current densityon the leaching of gold within the solution has been investigated. Theinfluence of the ratio S:L on gold extraction during electroleaching has beenstudied and the specific rate of gold leaching with different variations of theparameters has been defined. The sorption behavior of gold thiosulfatecomplexes on the anion exchanger AM-2B at various concentrations of sodiumthiosulfate taken from model solutions has been studied. Research into thecomparative study relating to the sorption of gold compounds from complexproductive solutions used in electrochemical leaching has been conducted.
