ABSTRACT:
A process for the recovery of mineral values by froth flotation in an aqueous medium employing a novel frother. Frothers prepared by Michael addition between alpha, beta-unsaturated ethylenic compounds and either alcohols, amines or mercaptans or by the condensation of HCN, aldehydes/ketones with either alcohols, amines or mercaptans have been found to be effective in the froth flotation system and capable of reducing the required collector consumption.
