2 天前  Nickel concentrates may be leached with sulfuric acid or ammonia, or they may be dried and smelted in flash and bath processes, as is the case with copper. Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickel-iron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is

Nickel sulphide concentrate processing via low

This study aims to identify the interaction products of sulphide nickel concentrate components with sodium chloride at temperatures of 400–450 °C. Thermodynamic studies have demonstrated that nickel sulphates, chlorides, and oxides are the probable nickel-containing products of the interaction between nickel sulphide and sodium chloride in the presence of oxygen.

Oxidation of nickel sulfide SpringerLink

1984-1-1  In the oxidation of nickel sulfide ofx s = 0.44 at 973 and 1023 K, the reaction proceeded irregularly to the interior of the sulfide core with the evolution of SO 2 gas, and a porous oxide layer was formed, due to the high sulfur activity of nickel sulfide. For the same reason, this oxidation was also accompanied by the dissociation of nickel sulfide.

Oxidation of nickel sulfide SpringerLink

The oxidation of nickel sulfide whose atomic fraction of sulfur,x s, is 0.40 to 0.44 was studied in a mixed O2-N2 gas stream at 923, 973, and 1023 K. The oxygen partial pressure was maintained at 2.0 x 104 Pa. In the oxidation of nickel sulfide ofx s = 0.40 and 0.41, a dense NiO layer was formed on the sulfide surface without the evolution of SO2 gas, because of the low sulfur activity.

2021-5-1  High-grade nickel oxides are produced by fluid-bed roasting and chlorine-hydrogen reduction of nickel matte. High-purity nickel pellets are produced by using vapour processes, an example of this is the carbonyl process: the copper and precious metals remain as a pyrophoric residue, which requires separate treatment.
