In gold leaching operations they can cause carbon fouling or interfere with Merrill-Crowe. Fines are notorious for being difficult to selectively float as well as degrading the selective flotation of coarser particles when they are intermixed.
WebJun 5, 2024 · 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.
