Selective sulphidation and flotation of nickel from a ...

2013-12-1  Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 6–8% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues with fine particle grinding and flotation.

Biosorptive flotation of nickel and aluminum ions from ...

2011-9-15  Abstract. Air flotation is an efficient way to separate light particulates and oils from wastewaters. Nickel (II) and aluminum (III) removal by the combined biosorption and flotation process named biosorptive flotation was studied in laboratory scale. The Rhodococcus opacus strain was used to assist the removal of the toxic metals by biosorption.

A New Process for Cobalt Nickel Separation

2015-11-20  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

role of sodium hexametaphosphate in flotation of a

The nickel grade of the ore sample used in this study was 1.35%. Approximately 96% of the nickel in the ore was in the form of pentlandite, and could be recovered by true flotation. The remaining 4% of nickel distributed in non-sulfide minerals, which could only be recovered by the entrainment mechanism or as composites with pentlandite.

2014-5-1  Pyrrhotite (Po) is one of the most abundant sulfide minerals in processing industry and must be rejected in most cases. Particularly, Po rejection and its selectivity against pentlandite (Pn) have long been a challenge due to similarities in the mineral composition of the two minerals and the collectorless flotation characteristics of Po. Xanthates have been widely used to promote sulfide ...
