METHOD TO EXTRACT COPPER AND MOLYBDENUM FROM SULFIDE COPPER-MOLYBDENUM ORES

摘要

FIELD: metallurgy. ^ SUBSTANCE: method includes main floatation with several rewashes by sulphydric and apolar collectors to produce a collective crude copper-molybdenum concentrate. Then its treatment with a reagent is carried out, such as sodium sulphide, and selective floatation to produce a foamed molybdenum-containing product and a chamber copper-containing concentrate. When processing a crude copper-molybdenum concentrate, a combination of sodium sulfide and sodium thioantimonate at the ratio of 4:11:1. ^ EFFECT: higher extraction of copper and molybdenum. ^ 1 tbl
