Flotation Of A Copper Sulphide Ore From Okiep Using Thiol

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

Flotation of a variety of non-sulphide and mixed sulphide plus non-sulphide copper ores is disclosed. Stabilization of non-sulphide copper mineral surfaces by sulphidization is initially required and a selective complexing agent able to complex with the copper sulphide surface is then added as conditioner. Diphenylguanidine proved to be a highly selective and fast acting surface conditioner ...
