Technology for the hydrometallurgical processing of a complex multicomponent sulfide-based raw material

Abstract

An analysis of the methods currently used for the metallurgical processing of polymetallic middlings from the beneficiation of sulfide ores shows that the oxidant which is the most promising for use as an agent to leach the middlings is nitric acid. A technology is developed to process hard-to-decompose middlings with the use of nitric acid. © 2013 Springer Science+Business Media New York.
