Some plants use bulk flotation in an acid pH environment which is achieved using SO2 or H2SO4. Separation of the bulk concentrate copper and nickel minerals is generally accomplished by flotation of the copper from pentlandite and nickel-bearing iron sulphides which report to the flotation tails.

The presence of a nickel sulphide mineral millerite -NiS has a significant impact on the CuNi flotation separation efficiency in the plant operations.
This process characterized by easier operation, longer flotation time, fewer concentrate flotation and process concentrate ore from different stages of separation, which can recovery nickel ore as soon as possible in the flotation process. The solution of copper-sulfide nickel ore get nickel grade of
International Nickel INCO and Sherritt Gordon use a bulk CuNi float pictured below, followed by selective flotation of the two elements into separate concentrates. Other Canadian producers leave separation to the smelters. Flotation of a CopperNickel Ore Containing Pyrrhotite is as follows
Feb 25, 2019 The high-grade nickel concentrate produced during the testing program approximates the composition of pure awaruite, a nickel-iron alloy comprised of approximately 75 Ni and 25 Fe. Phase 2 testing confirmed that the separation of nickel from a bulk Ni-Fe concentrate can be achieved using traditional flotation processes.

A new depressant for use in enhanced separation of polymetallic sulphides is described. The depressant agent is used in conjunction with conventional collector agents and frothing agents in the flotation separation of copper, nickel, lead, zinc sulphides by depressing iron sulphides such as pyrrhotite, pyrite and marcasite in the tailing.
Flotation Separator Flotation machine, in mineral processing, is mainly used for the separation of copper, zinc, lead, nickel, gold and other non-ferrous metals, and it can also be used for ferrous metals, non-metallic rough selection. As they are more efficient, especially in the finer size ranges, they also need less floor space and ...
excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative if the ore can be concentrated by flotation, matte smelting is used instead of leaching.

A hydrometallurgical process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. The process involves forming a slurry of the sulfidic flotation concentrate in an acid solution, and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach.
Flotation behavior of nickel sulfide ore in a cyclonic flotation column 775 In the flotation system, the density of mineralized bubbles m is much smaller than that of the fluid , and generally speaking, the density of particles p that cannot adhere to bubbles is much higher than that of the fluid .
Conventional flotation technology has historically failed to achieve high recoveries when treating 15 m particles Lynch et al, 1981. The new StackCell flotation technology was developed to specifically target this particle size range, and was tested at pilot plant scale at Mt Keith Nickel Concentrator.
A nickel-copper sulfide system usually coexists with serpentine in deposits.

Nickel sulRde minerals such as pentlandite can, ingeneral, be separated from their gangue bySotationusing a thiol group of collectors like xanthates andalkyl dithiophosphates in the presence of variety ofactivators, depressants and dispersants. Since nickelsulRdes contain other sulRdes such as pyrrhotite, pent-landite and chalcopyrite, the enrichment of nickel isgenerally carried out by two
This combination of flotation and smelting effectively removes most of the deleterious impurities, and thus produces a nickel-cobalt matte suitable for leaching and eventual Cyanex 272 separation of nickel and cobalt. Historically of course almost all nickel sulphide ores have been treated in this way however, not all sulphide ores
In nickel-copper sulfide ore processing, serpentine is a common gangue mineral encountered in complex sulfide ores and can easily cause entrainment during flotation . Large amounts of serpentine in the flotation concentrate reduces the effectiveness of smelting, often resulting in the imposition of smelter penalties on mineral processing companies 2 .
