The reduction of nickel from low-grade nickel laterite ore ...

In this study, the nickel extraction from low-grade nickel laterite ore was performed using a solid-state deoxidisation method. It was shown that an α Ni of greater than 90% could be obtained from nickel laterite ore using a CO and CO 2 mixture as a gaseous reductant, and an α Ni of up to 80% could be obtained from nickel laterite ore using anthracite as a solid reductant.

Nickel Laterite's Integral Role in the Coming Nickel Boom ...

Nickel laterite ore processing depends on the zone from which the ore is mined. As outlined earlier, each zone within a laterite deposit is very different in its chemical composition and, therefore, restricts the processing technique that can be used to extract the nickel.

Nickel Deposits of - pubs.usgs.gov

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.
