Abstract
The hydrometallurgical processing of industrial converter mattes with the copper-to-nickel concentration ratios (Ni : Cu) of 2 : 1 and 3 : 4 is studied in order to demonstrate the advantages of hydrometallurgical processing methods, which can improve the environment and increase the number of important components extracted from raw materials. The results obtained indicate the possibility of direct leaching of the converter mattes with different copper and nickel contents under atmospheric conditions. During leaching, the extraction of to 94–95% nickel into a solution takes place; the solution is subjected to electroextraction; and the solid residue (copper cake) contains to 95% copper of its initial content in the converter matte. A high copper content in the converter matte is found to decrease the extraction of nickel into the solution.
