METHOD FOR FLOTATION OF SULPHIDE COPPER-NICKEL ORES Russian patent published in 2024 - IPC B03D1/00 

Abstract RU 2828519 C1

FIELD: various technological processes.

SUBSTANCE: proposed invention relates to the field of minerals dressing, in particular to flotation methods of dressing, and can be used at dressing of sulphide copper-nickel ores. Method of flotation of sulphide copper-nickel ores includes main and control flotation in the presence of soda ash to create pH, copper sulphate and a collector. Collector used is a mono-derivative of phthalic acid or a mixture thereof with butyl xanthate in ratio of 30:70 wt.% to 70:30 wt.% in combination with a foaming agent butyl aeroflot. Mono-derivative of phthalic acid used is monohydrazide of phthalic acid, or monoamide of phthalic acid, or monohydroxyamide of phthalic acid, or monobutylamide of phthalic acid.

EFFECT: higher efficiency of flotation of sulphide copper-nickel ores.
