Abstract

A hydrometallurgical method for processing copper-smelting slags with the help of ammonium chloride is proposed. A production flowchart of the process stage is developed. Breakdown of the slag with the help of ammonium chloride is investigated and recommendations on the equipment implementation of the process are given. The copper-smelting slag is formed by minerals Fe2SiO4, Zn2SiO4, CuFe2O4, and Ca2SiO4. Breakdown should be performed at 280°C for 4 h with constant stirring and ratio slag: ammonium chloride = 1: 2.
