Abstract

The processes occurring at nitric acid leaching of copper-electrolyte slimes are described. The influence of firing temperature and concentration of nitric acid on the degree of transition of silver and related elements into solution is investigated. Optimal modes providing high extraction of silver into solution and concentration of gold in the insoluble residue have been established.
