ABSTRACT In Part II, the correlation between Fe–Ni grain growth and characteristic fusion temperatures of the Na2SO4–laterite mixtures, and phase transformations of the reduced pellets were investigated. For the mechanism of sodium sulphate, Na+ is able to liberate the hosted nickel and iron within lizardite, while SO42– is the sulphur source for the …

Nickel sulphide ore subjected to this investigation was taken from the Marmara district of Turkey, where widespread chromite mineralization can be observed. Some amounts of magnetite and chromite exist in the ore together with sulphide and oxide type nickel minerals. The ore sample contains 1.32% Ni, 10.79% SiO2, 78.39% Fe2O3, 1.3 g/t Ag, and 1.0 g/t Au. …

As shown in Fig. 15, the operations includes processes including ore beneficiation and blending, reduction roasting, and leaching of roasted ore in the ammoniacal solvent. Then, there is separation of Ni and Co using solvent extraction, and precipitation from a solution of basic nickel carbonate (BNC).

Nickel plays a critical role in the mining industry. However, the presence of nickel in the primary source of sulfide minerals is decreasing. Focus has since turned to laterite ore, which contains up to 80% Ni metal. The purpose of this study was to optimize nickel leaching using sulfuric acid and conduct a kinetic analysis to discover the mechanism that best controls …

Nickel laterite HPAL circuits are known for their complexity and have presented a large number of challenges to process engineers worldwide. An attitude commonly encountered by the author is that the beneficiation of the ore is relatively simple and that the difficult problems are in the realms of hydrometallurgy. On a number of occasions beneficiation has become the 'poor …

For example, in a nickel-cobalt laterite deposit in New South Wales, Australia, gravity separation followed by magnetic separation resulted in upgrading nickel from 0.9% to 1.1% at 57% recovery (Aral, 2013). Furthermore, Muir and Johnson (2006) demonstrated that in physical beneficiation using gravity, particle size is the key parameter.
