Chromite refining process
WebChromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize from cooling magma. Because of their density, chromite crystals fall to the bottom of the … WebThe process followed by another magnetic separation, thus the Cr/Fe ratio was increased from 0.9 to 1.6. The reduction process used coconut shell charcoal as reductant and limestone as an additive. The beneficiated sand chromite was briquette using bentonite as a binder in 2 wt.% before it was smelted in a submerged
