BREAKDOWN OF COPPER-SMELTING SLAG BY AMMONIA CHLORIDE
https://doi.org/10.17073/0021-3438-2013-5-9-12
Abstract
A hydrometallurgical method of copper-smelting slag processing by means of ammonium chloride is proposed. A basic processing diagram has been developed. Investigations of slag decomposition by ammonium chloride are conducted and the recommendations concerning the process implementation are given. Minerals, which form copper-smelting slag, are Fe2SiO4, Zn2SiO4, CuFe2O4 and Ca2SiO4. The decomposition should be carried out at temperature of 280 °C for 4 hours with continuous agitation and at slag/ammonium chloride ratio of 1 : 2.
