Cleaner bank recoveries also indicate true flotation of arsenic minerals, but to a higher degree than that of the rougher bank. This indicates that selective flotation of copper minerals against arsenic minerals may be more difficult. Download : Download full-size image; Fig. 4.

Selective Flotation Mineral Processing & Metallurgy

Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the lab. In selective flotation, less is more!

Selective oxidation of minerals was investigated as a means to separate by flotation the copper sulfide minerals of chalcocite, covellite and chalcopyrite from the arsenic copper sulfide minerals of enargite and tennantite in mixed mineral systems. It was found that a separation of these minerals could be feasible after selective oxidation of

The selective flotation of enargite from other copper

The floatability of enargite (3Cu 2 S.As 2 S 5) has been determined as a function of pulp potential to establish whether the flotation behaviour of the mineral differs sufficiently from that of other copper minerals thus offering the prospect of rejecting arsenic from the Tampakan ore by potential control during flotation..

Research on separation of arsenic-bearing copper sulphides from other copper sulphides, by flotation, indicates that Eh control shows promising results for separating arsenic copper sulphide from other copper sulphides, due to the strong Eh dependence of arsenic mineral flotation.

Copper concentrates for 2013 both measured about 0.44 percent arsenic content. This is above typical levels where penalties occur.
