Dr Robin Hill is internationally acclaimed for his outstanding research on the geological factors responsible for the formation of magmatic nickel-copper sulphide ore-deposits and the development of successful exploration strategies for these deposits. The research emphasised the need to consider the physical volcanology of the host ultramafic rocks when planning strategies for exploration.

Some of the world class nickel ore are known for grading between 2 to 3% Ni, and some of the best grade of nickel composition rocks are obtained from the bottom of the blanket. These foremost nickel grades which are deemed high, are commonly associated with serpentine garnierite cement blocks of peridotite, or the serpentinite replacement of it.

Kambalda type komatiitic nickel ore deposits

Kambalda-type ore deposits are distinctive in that the deposition of nickel sulfides occurs within the lava flow channel upon the palaeosurface. This is distinct from other komatiite and ultramafic associated NiS ore deposits, where nickel sulfide accumulates within the lava conduit or upon the floor or within a subvolcanic lava chamber.

Mineral Commodity Report 10 Nickel

Nickel ranks about 22nd in natural abundance among elements in crustal rock, but about 5th in the earth as a whole. It is concentrated in ultramafic igneous rocks (0.10.3% Ni) compared with silicic igneous rocks (0.006% Ni). The most important ore minerals are the sulphides pentlandite and pyrrhotite, and the oxide garnierite (Table 1

Nickle vs. Nickel What's the difference? Ask Difference

Nickel was first isolated and classified as a chemical element in 1751 by Axel Fredrik Cronstedt, who initially mistook the ore for a copper mineral, in the cobalt mines of Los, Hlsingland, Sweden. The element's name comes from a mischievous sprite of German miner mythology, Nickel (similar to Old Nick), who personified the fact that copper
