The life of Ni - Nickel Institute
The world’s nickel resources are currently estimated at almost 300 million tons. Australia, Indonesia, South Africa, Russia and Canada account for more than 50% of the global nickel resources. Economic concentrations of nickel occur in sulphide and in laterite-type ore deposits. Despite the fact that nickel mining has significantly increased over
Laterite - Wikipedia
26.01.2004 · Laterites are a source of aluminium ore; the ore exists largely in clay minerals and the hydroxides, gibbsite, boehmite, and diaspore, which resembles the composition of bauxite. In Northern Ireland they once provided a major source of iron and aluminium ores. Laterite ores also were the early major source of nickel
KINETIC MODELS OF NICKEL LATERITE ORE …
The subject of this study is leaching process of nickel-bearing laterite ore from Ržanovo, R. Macedonia. The influence of sulfuric acid concentration (0.5, 1 and 3 M H2SO4) on the extracted Ni (%, wt.) was studied. The leaching process intensified by magnetic stirring at different temperatures (298, 323, 348 and 363 K) in the time interval of 120 min. was performed.

Extraction of Nickel, Cobalt and Iron from Laterite …
Primary nickel is produced from both lateritic and sulfidic ores. Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron (< 15 % Fe) ores containing 1.7 — 2.3% Ni are treated by pyrometallurgical processes to produce ferronickel or matte ...
