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.

The flotation of gersdorffite in sulphide nickel systems

2009-10-1  The relationship between gersdorffite flotation and pulp potential at pH 9 is shown in Fig. 4 as a plot of mineral recovery at 8 min against pulp potential. The air-set potential for this system was about. + 200 mV SHE at pH 9.. The data indicate that the strong response seen at the air-set potential extends to more oxidising conditions up to + 400 mV SHE.

5 Factors Affecting Silica Sand Flotation

2020-11-23  Flotation is one of the commonly used methods for silica sand beneficiation. It is mainly used to remove mica and feldspar minerals that are symbiotic with silica sand. However, in the actual production process, the flotation process will be affected by many factors, including: feed size, slurry temperature, slurry liquid chemical composition, flotation reagents and other flotation conditions.

Pentlandite oxidation in the flotation of a complex nickel

Research highlights Nickel recovery was low in the flotation of both fine and coarse fractions in saline water. Oxidation occurred on both fine and coarse pentlandite particles. NaHS added during grinding improved both pentlandite and serpentine mineral flotation and deteriorated pentlandite separation from serpentine. Na 2 S 2 O 4 added during grinding improved pentlandite flotation without
