Element ratios in nickel sulphide exploration: vectoring towards ore

Within the channellized ore environment, elevated Ni and low Cr values are observed in the lower flow unit of the ultramafic pile (Fig. 4 a). Nickel concentrations exceed those of Cr, so the Ni : Cr ratio is >1. Higher in the ultramafic pile, Ni decreases as Cr increases. Download : Download full-size image; Fig. 4.

Nickel | BHP

Nickel sulphide ore is mined at our open-cut and underground operations in the Northern Goldfields of Western Australia. It is then crushed and concentrated using nickel sulphide flotation technology, before being dried and railed to the Kalgoorlie Nickel Smelter, where it is fed to a flash furnace. This produces a granulated matte product ...

Unlocking millions of tonnes of nickel

Naturally found in two forms, laterite and sulphide deposits, the majority of nickel currently mined is nickel sulphide, because it is easier and cheaper to process. [Image changes to a pile of manufactured nickel rods and then to a rock of nickel sulphide ore] However, the majority of the world's reserves, around 70%, are laterites.


The bacterial community structure during bioleaching of a …

The focus of this study is to characterize the bacterial community structure present during stirred-tank bioleaching of a low-grade nickel sulphide ore at different temperatures (5 to 45 °C) and pH levels (3 and 5).This is a continuation of previous work, which was designed to assess the technical feasibility of applying elevated-pH …


Nickel Sulfide

Nickel* CATHERINE KLEIN, MAX COSTA, in Handbook on the Toxicology of Metals (Third Edition), 2007. 3.1 Production. Nickel exists as a natural earth element, primarily in sulfide or oxide ores that are mined underground or in open pits. It is the 24th most abundant element on earth, with the greatest deposits of nickel ores in Canada, Siberia, and New …

Intensification of Sulfide Copper-Nickel Ore Heap Leaching …

The rate of solution filtration through a layer of ore was determined in percolators with a volume of 3 liters with an ore weight of 3 kg and layer thickness ≈600 mm. Ore size was determined by leaching for 35 days in troughs with S:L = 1:3 by sulfuric acid solution with a concentration of 10 g/liter and bioreagent of 10 g/liter with respect to …


Controllable Phase Transformation in Extracting Valuable

In this work, a two-stage sulphuric acid roasting and water leaching system was chosen to extract valuable metals from Chinese low-grade nickel sulphide ore. By optimizing the two-stage roasting process, first roasting temperature at 295°C with particle size of 80–91 μm with an acid-ore ratio of 1.1:1 for 2 h, and second roasting temperature at 620°C for 2 h, it …

Challenges in processing nickel laterite ores by flotation

It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and …
