Abstract

FIELD: non-ferrous metallurgy. SUBSTANCE: cupric sulfide is loaded in carbonate smelt under temperature of 873 - 1520 C and kept for 1 - 4.5 hours. EFFECT: production of copper from cupric sulfide without carbon reducer usage and decrease of outgoing gases volume from smelt of alkaline metals salts.

Изобретение относится к области цветной металлургии. Целью изобретения является увеличение производительности, снижение капиталовложений, улучшение экологической обстановки при электролизе щелочно-карбонатного расплава. В расплаве растворяют оксид кадмия в количестве 2 - 6% и процесс ведут при катодной плотности тока 0,2 - 1,5 А/см2, анодной плотности 0,25 - 1,9 А/см2. Индиферентный анод и жидкий или индиферентный твердый катод с межполюсным расстоянием 2 - 5 см.The invention relates to the field of non-ferrous metallurgy. The aim of the invention is to increase productivity, reduce investment, improve the environmental situation during the electrolysis of alkaline-carbonate melt. Cadmium oxide is dissolved in the melt in an amount of 2-6% and the process is carried out at a cathodic current density of 0.2-1.5 A / cm 2 , anode density of 0.25-1.9 A / cm 2 . Indifferent anode and liquid or indifferent solid cathode with an interpolar distance of 2 - 5 cm.
