Jul 12, 2016· In this sense, the state of the art lacks a method for a) improving the selectivity and recovery in the flotation of Cu/Ni sulphide minerals which are associated with iron sulphides, and b) reducing or eliminating the use of problematic polyamine chemicals (such as DETA) to minimize the negative impact on the environment .
3 Nickel Sulphide Resources1 Nickel resources are typically classified as sulphides or laterit Approximately 73% of the world’s nickel resources are estimated to be contained in laterites while 27% are as classified as sulphide Currently, some 37% of the world’s nickel supply is derived from sulphide resources and almost all

The selective flotation of pentlandite from a nickel ore Senior, GD; Trahar, WJ; Guy, PJ 1995-06-01 00:00:00 Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to maximise nickel recovery and talc rejection but which does not reject .
AbstractA new method for the treatment of Ni–Cu sulphides ores from the Sudbury region by differential flotation is presented The method exploits the ease of chalcopyrite floatability in complete or virtual absence of collector, but in the presence of sulphur dioxide, an effectivecomplexing agent such as diethylenetriamine (DETA) and a frother
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
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing, paper recycling and waste-water treatment industri Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century
Jun 06, 1972· Flotation of sulphide minerals from their ores is achieved by a process in which two or more conditioning steps are carried out prior to a froth flotation step The first step comprises conditioning a , FLOTATION OF COPPER-NICKEL SULFIDE ORES , It's chemical analysis was 0525 percent Ni and 045 percent Cu
For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching This combination of flotation and smelting effectively removes most of the deleterious impurities, and thus produces a nickel-cobalt matte suitable for
