Mixed copper sulfide and oxide (3 replies)

What reagents(i.e collector and frother) can you recommend to simultaneously float copper sulfides and copper oxides?

Mr. Gaco

It is not possible to activate the same time both with any reagent, maybe if the copper oxide this covered with sulfides can float or any ore sulfide linked with copper oxide this can be possible.

Good luck

Contact http://www.oxflo.com their Oxfloat H88L can float both copper oxides and sulfides without Xanthate or NaHS. It also floats gold. This powerful oxide collector is from South Africa and not known to most in the Americas.

It depends what your definition of together/simultaneously is? Sulphides will always float faster than oxides. You float sulphides with PAX and them add your Hydroxamate to get oxides (add NaHS if your material responds to the sulfidiser).

In a traditional way, sulphide and oxide copper minerals do not recover at the same rate. You typically handle their flotation in a sequential manner: sulphide species #1 followed by oxide minerals.

Marshal is correct, the only comment I want to make is you will not likely be able to use your water over again, no return water except to the oxide circuit. Oxide flotation return water will cause havoc in your sulfide circuit.
