ABSTRACT:
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 which converted both sulphide and sulphidized copper minerals to an oleophilic condition. Addition of relatively small amounts of emulsified, non-polar oil completed the selective conversion of copper minerals to strongly hydrophobic and floatable condition. Favorable results have been obtained on a series of ores ranging from low grade malachite-chal-copyrite ores to high grade cuprite-malachite-chalcocite and brochantite ores.
