Abstract

The flotation process for removing mineral impurities, especially silicates, from ores comprises passing air through an aqueous suspension of the ground ore in the presence of a flotation aid and separating off the foam plus the impurities. The collector components used in the flotation aid comprise quaternised ester compounds (esterquats) of formula (I), (II) and/or (III), optionally with other anionic, cationic, amphoteric and/or non-ionic substances. In the formulae: R1CO, R5CO and R9CO = 6-24C acyl; R2, R3, R6 and R10 = H or 6-24C acyl; R4 = 1-4C alkyl or -(CH2CH2O)qH, where q = 1-12; R7, R8, R11, R12 and R13 = 1-4C alkyl; (m + n + p) or (m + n) = 0 or 1-12; and X = halide, alkylsulphate or alkylphosphate.
