Acidic medium flotation separation of chromite from

1997-11-1  It was demonstrated that, when Na-oleate is used as collector, chromite, olivine and serpentine can be separated at pH 2.5 and/or pH 5.5 when employing ethylene-diamine tetraacetate (EDTA) on previously deslimed material. This approach ensures flotation concentrates with a Cr2O3 content better than 50% with a recovery of more than 75%.

Gravity and heavy medium separation GTK
