FLOTATION CONCENTRATION PROCESS OF OXIDIZED CLAYEY GOLD-BEARING ORES

摘要

FIELD: gold-bearing ore dressing. ;SUBSTANCE: gold is recovered from oxidized clayey gold-bearing ores using flotation concentration process under liquid hydrocarbon layer after wet crushing and treatment with reagents: collector and foaming agent. Crushing of ore is effected to achieve 94-95% of ore as fineness class -0.044 mm. Collector utilized is sodium butyl xanthogenate, which is consumed in amount 5500-6000 g/t ore.;EFFECT: enhanced process efficiency.;1 tbl, 8 ex
