The effects of oxidation on the floation of chromite and olivine were studied in an effort to improve chromite recovery from domestic sources. The flotation behavior of pure chromite, pure olivine, and a chromite gravity concentrate were investigated. Freshly prepared chromite floated well between pH 2.2 and pH 4.5, but floated poorly at pH greater than 5.
