The selective flotation of pentlandite from a nickel ore
Abstract. Nickel sulphide ores containing pentlandite, pyrrhotite and talc have traditionally been treated by bulk sulphide flotation, an approach which seeks to The mineralogy and texture of Ni-sulfide ores at the Nkomati nickel mine are highly variable, and this results in often erratic nickel recovery at the mine. The variability of the ore presents an opportunity to study the influence of grind size on the flotation-based recovery of Ni in highly heterogeneous sulfide ores, which would be applicable to this A Process Mineralogical Evaluation of Chromite at the Nkomati Nickel

A Process Mineralogical Evaluation of Chromite at the Nkomati Nickel
A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite.

Nickel processing Extraction, Refining, Alloying Britannica
Nickel processing Extraction, Refining, Alloying: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating 7.Indian nickel market India does not have any history related to the metal nickel. In India nickel is vary law grade deposit and there is no processing plant. But as one of the fastest developing nations of the world, Indian demand for stainless steel and consequently nickel has been rising at a high rate.

However, for all practical purposes, due to the inadequacy of a single ore type to meet the daily run of mine ore requirements, grinds of P77 at 75 µm and P80 at 75 µm would be ideal for processing ores as a composite from the MMZ and the PCMZ, respectively; (4) The P77 at 75 µm grind produced the highest nickel grades in the Bleb_MG, Dis_MG, A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite.
