Abstract

1307320 Froth flotation ANACONDA CO 18 Jan 1971 [20 Jan 1970] 2315/71 Heading B2H Molybdenum sulphide is separated and recovered from copper ore concentrates containing molybdenum sulphide and copper sulphide by conditioning an aqueous pulp of the copper ore concentrates with a collector for molybdenum sulphide and a Nokes-type depressant for copper sulphide, and subjecting the conditioned pulp to froth flotation in which a gas, which is non-reative with the Nokestype depressant, is employed as the frothproducing gas to effect recovery of a molybdenum concentrate in the flotation overflow and recovery of a copper concentrate in the flotation underflow while maintaining the e.m.f. of the aqueous pulp above a predetermined value to maintain the effectiveness of the depressant. A Nokes-type depressant is defined as a reaction product of two or more inorganic compounds, said reaction product containing bivalent sulphur, a caustic cation, and phosphorus, arsenic or antimony. The froth-producing gas may be nitrogen, Freon (Trade Mark), an inert gas such as helium or argon, or mixtures thereof. The aqueous pulp may contain a sufficient amount of the depressant for copper sulphide to maintain the e.m.f. of the pulp above-200 millivolts when measured with a platinum electrode with reference to a standard GP (calomel) glass electrode. Examples are given.
