Flotation of Chromite Ore

Deslimed chromite ore was floated at pH 1.5 to 5.5 using a long-chain fatty-acid collector and soluble fluoride ions as a silicate depressant. The Havens method was later modified slightly to permit flotation without preliminary desliming. This was done by preconditioning the pulp with fuel oil and fluoride ion.
