Flotation of a variety of non-sulphide and mixed sulphide plus non-sulphide copper ores is disclosed. Stabilization of non-sulphide copper mineral surfaces by sulphidization is initially required and a selective complexing agent able to complex with the copper sulphide surface is then added as conditioner. Diphenylguanidine proved to be a highly selective and fast acting surface conditioner

Typical lead-copper-zinc sulphide minerals were found hard to be separated selectively by froth flotation in the plant practice operation due to part of sphalerite was progressively entrapped into lead-copper bulk flotation. A series of de-zincing on lead-copper flotation tests has been conducted in the laboratory to reduce unwanted zinc content

Aug 12, 2015 Sodium cyanide is occasionally substituted for lime in the flotation of a sulphide copper ore containing pyrite, since it has a much greater depressing effect on the pyrite than on the copper minerals. Xanthate is generally employed to bring up the copper sulphides, its addition being balanced against that of the cyanide to effect a profitable

Differential flotation sequence: A differential copper-cobalt flotation separation which begins with selective copper flotation by raising the slurry pH to 10 with lime and using a dithiophosphate copper collector. The tails produced in the first differential flotation step is followed by a pyrite and pyrrhotite flotation stage using xanthate

Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated)

Where oxide and sulphide cobalt-bearing copper minerals occur together, efficient recovery of copper and cobalt is known to be extremely difficult. This study investigates the flotation behaviour of a mixed oxide-sulphide ore where copper is hosted in sulphides phases such as bornite, chalcopyrite and chalcocite, and oxide phases such as
