METHOD FOR PROCESSING COBALT-NICKEL-COPPER arsenide-sulphide ores

摘要

A method of processing a cobalt-copper-nickel ores by collective flotation redox calcining cobalt-nickel concentrate, characterized in that the oxidizing roasting of cobalt-nickel concentrate are air enriched with nitrogen oxides or calcined gas passed dedusting and absorption of sulfur dioxide, oxygen-enriched and nitrogen oxides.
