Feb 07, 2020 In this research, a laterite ore sample, containing Ni, Co, and Fe, was employed to study the recovery of nickel and cobalt. Thus, the effect of calcination, acid concentration, percent solids, and stirring rate on nickel and cobalt recoveries from an iron-rich laterite sample was investigated.

A characteristic feature of cobalt is its ability to form commercial concentrations in deposits of other metals (nickel, copper, and iron), where it occurs mainly in cobalt-containing ore minerals (pyrite, pentlandite, and asbolites), rather than only in the form of strictly cobaltiferous minerals. A distinction is made among arsenic, sulfur ...

nickel ore deposits are closely associated with mafic and ultramafic in trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle.

Feb 01, 2020 1. Introduction. Nickel (Ni) and cobalt (Co) are amongst the critically rare metals due to their large industrial usage and vital application in rechargeable batteries , , .The laterite ores are accounted for 70% of Ni reserves worldwide but 60% of the global Ni production is still contributed by the sulfide ores , .Due to the depletion of Ni-containing sulfide ores, increasing attention is ...

Nickel-cobalt lateritic ores can be treated by either hydrometallurgical processes or pyrometallurgical processes, such as matte or ferronickel smelting, which require the entire ore to be melted and the metal values to be separated from the residual components of the ore. The hydrometallurgical process for laterite ore can use sulfuric acid or ...
