Home / Serpentine Comminution Engineering
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.
