Flotation of Chromite Ore
· Deslimed chromite ore was floated at pH to using a longchain fattyacid collector and soluble fluoride ions as a silie 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. The chromite collector was a mixture of a longchain fatty acid ....
