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. WebInteraction effects between aeration rate and froth have been reported by Venkatesan and Harris (2014). The work showed that interaction effects were significant at conditions of high air flow rate (40 m/s ) and cell level (max. 95 % cell level).
