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
