2019-5-15  3.1 Chrome magnetic separation process. The chrome raw ore is a flotation tail ore, which is mainly formed in the chromite, and the chromite is the target recovering mineral. The dissociation degree of ferrochromium ore is low, and it has a weak magnetic property. First of all, magnetic separation processing to separate chromite.

Chromite ore beneficiation - Idaho Research Foundation, Inc.

Chromite ore beneficiation. Disclosed is a process for beneficiating chromite ore. The process can also be used to remove SO 2 from SO 2 -air mixtures which would ordinarily be vented. The chromite ore is pulverized and preferably mixed with sodium sulfate. Ammonium carbonate can also be added for subsequent vaporization to increase porosity.
