Thiol collectors are used in the froth flotation of copper sulphide ores. The xanthates, dithio-phosphates and dithiocarbamates are classes of thiol collectors that each form different surface products on different copper sulphide minerals. It has been shown that the use of mixtures of thiol collectors can have benefits over the
