Impact of acid surface pretreatment on the flotation of ilmenite and titanaugite and its functional mechanism

The effect of acid surface pretreatment on the flotation behaviors of ilmenite and titanaugite was investigated with BHA collector and Pb2+ activator. The flotation recovery of ilmenite improved from 62.56% to 84.68% at pH 8.0 after pretreated with H2SO4 solution, while that of titanaugite decreased...
