    Chromite is beneficiated by froth flotation with an amine reagent. The ore is ground to 30-210 micrometer pulped to 24-29 pct solids acidified to ph 2.5 With h2so4 and floated with 0.5-1.0 Lb amine collector/ton of ore.Thus chromite ore was ground to -100 mesh deslimed to >30 micrometer and pulped to 24 pct solids.
