Microwave Treatment of Ultramafic Nickel Ores: Heating

Ultramafic nickel ores are difficult to process because they contain serpentine, an anisotropic mineral with a nonspherical morphology and multiple pH-dependent surface charges. Dehydroxylation of serpentine in ultramafic nickel ores by microwave treatment is proposed to improve the processability of these ores. Upon heating, serpentine is converted to olivine, an isotropic mineral that is

Microwave heating of ultramafic nickel ores and

Apr 01, 2014· Two low-grade ultramafic nickel ores were used in this study: the “OK ore” (containing 0.26 wt.% Ni) from the Okanogan nickel deposit in Washington State, USA, and the “Pipe ore” (containing 0.23 wt.% Ni) from the Thomson Nickel Belt in Manitoba, Canada.

Effect of microwave pre-treatment on ultramafic nickel ore

Jun 01, 2014· At Vale, ultramafic nickel ore slurries have had to be diluted to 20 wt.% solids to achieve satisfactory flotation results (Patra et al., 2010). If the flotation pulp density could be increased from 20 to 30 wt.% solids by microwave pre-treatment, the volume of the pulp could be reduced by 40%, likely resulting in significant savings in

Ultramafic nickel laterites in Indonesia (Sulawesi

Extraction of both natural gas and valuable metal ore deposits is a major contributor to deforestation in Sulawesi, particularly the mining of nickel, across the 15,400-km 2 ultramafic outcrop

Nickel Deposits of USGS

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.

2.5 Mafic-ultramafic orthomagmatic mineral systems

Major critical commodities found within mafic-ultramafic orthomagmatic mineral systems include PGE, chromitite and V and Ti oxides. However, other crictical commodities, such as Mo, Se, Te, Co, and Sc, can also be associated with mineralisation in mafic-ultramafic ore bodies (Barnes and Lightfoot, 2005).
