Recovery of Ultrafine Pentlandite by Shear Flocculation
A sample of massive sulphide ore from the Kambalda region was separated using magnetic separation to obtain a high grade pentlandite concentrate (> 90 per cent). This was finely ground to produce a sample with particles of 50 per cent minus 10 um in size.
Recovery of Ultrafine Pentlandite by Shear Flocculation
Nickel flotation circuits currently experience difficulties in recovering fine particles of pentlandite less than ten microns. By agglomerating these particles using shear flocculation it is hoped to improve the recovery of these fine particles. A sample of massive sulphide ore from the Kambalda region was separated using magnetic separation to obtain a high grade pentlandite concentrate
The role of sodium oleate (NaOL) in the magnetic
Mar 01, 2019Fig. 1 shows magnetic separation recoveries of the single pentlandite (5 g) and serpentine (5 g) as a function of NaOL concentration with the addition of 4% magnetite (0.2 g) as magnetic seeds under a magnetic field intensity of 200 kA m 1. At a natural pulp pH of around 7.0, the recovery of pentlandite increased rapidly with increasing NaOL concentration.

The Separation of Pentlandite from Chalcopyrite
The grades and recoveries of nickel concentrates produced from sulfide ores can be significantly impacted by the ore mineral texture, the nickel tenor of the sulfides, and the polytype of pyrrhotite which may be either hexagonal (non magnetic) or monoclinic (magnetic).
How to Choose and Use Magnetic Separators
1. Magnet MaterIals styles perManent. Magnet material generally refers to the magnetic pressings or castings used to develop the magnetic field within the separator. This material may be cut and arranged in a linear fashion using other materials to create a magnetic circuit.
Magnetic separation of pentlandite from serpentine by
In this study, pentlandite was selectively separated from serpentine using magnetic coating technology by adjusting and optimizing pH, stirring speeds, magnetic field intensities, and dosages of sodium hexametaphosphate (SHMP) and sodium oleate (SO).
Enhancement of pentlandite surface magnetism and
new method of separating pentlandite from serpentine by magnetic coating. Surfaces of pentlandite were coated selectively by fine magnetite particles to enhance its magnetic property for magnetic separation. 2 Experimental The experimental samples, pentlandite, serpentine and magnetite were obtained from Jinchuan Group Co.,
The effect of polyether on the separation of pentlandite
The pentlandite sample was prepared using pentlandite rocks from Jinchuan, Gansu Province, China. This sample was passed through a magnetic separator three times to remove the magnetic pyrrhotite fraction. The non magnetic fraction containing the pentlandite was dry ground and screened. The 150 + 75 m fraction was used for the
Surface Modification of Pentlandite and Serpentine with
Separation of Pentlandite and Serpentine Mixtures by Selective Magnetic Coating. Figure 1 illustrates the separation of artificial mixtures of 10.0 g of pentlandite and 5.0 g of serpentine under a magnetic field intensity between 47 kA m1 and 247 kA m1 at the natural pH of 6.87.2.

How to Separate Millerite (NiS), from pentlandite
2) Re float the Cu Ni bulk con using PAX at pH 11 to 12 to float off the chalcopyrite into a copper con and depress the pentlandite into a nickel con. Not sure about the flotation kinetics of millerite and how it compares to those of pyrrhotite, chalcopyrite and pentlandite. But Google says millerite floats a bit better than pentlandite at pH 10.
