Studies on dialkyldithio-carbanate collectors with reference to sulphide minerals

Abstract

These studies have shown that the dithiocarbamates are not oxidised either in solution or at the surfaces of sulphide minerals. Such an oxidation is not a prerequisite for the adsorption of these collectors at the sulphide minerals. Dialkyldithiocarbamates are superior to alkyl xanthates in the selective flotation of sulphide minerals.
