Abstract: A method of using the synergy of multiple depressants to improve the depression of iron sulphide without compromising the recovery of the valuable sulphide minerals in the flotation of non-ferrous metal sulphides, while reducing or eliminating the use of environmentally problematic chemicals such as polyamines. The method has significant economic and environmental benefits. The multiple depressants comprise at least one organic polymer, at least one sulphur-containing compound and/or at least one nitrogen-containing organic compound.
