Copper Nickel Flotation. The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft.

Nickel sulfide - Wikipedia

Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide.Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.Aside from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as catalysts.

Flotation behavior of nickel sulfide ore in a cyclonic flotation column 775 In the flotation system, the density of mineralized bubbles (ρm) is much smaller than that of the fluid (ρ), and generally speaking, the density of particles (ρp) that cannot adhere to bubbles is much higher than that of the fluid (ρ).

what is differential flotation process for nickel and ...

In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. Nickel Wikipedia. Most sulfide deposits have traditionally been processed by concentration through a froth flotation process followed by pyrometallurgical extraction.

Nickel Sulfide - an overview | ScienceDirect Topics

Nickel sulfide is an insoluble carcinogen which is thought to act through the production of free radicals. Implanted nickel sulfide into C57BL/6 mice induced malignant fibrous histiocytomas and all tumors demonstrated hypermethylation of the tumor suppressor gene p16 (Govindarajan et al., 2002). Nickel also affects histone modification.

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.
