Pyrite Depression in Copper Flotation

2021-2-27 · The Pyrite Depression in a Copper Only Flotation circuit is simple enough. If your froth flotation system only tries to recover chalcopyrite-copper, you need to bring the plant’s pH up to the other side (right side) of the PYRITE curve. The more flotation

The depression of pyrite in selective flotation by ...

2016-10-1 · In the flotation of copper-activated pyrite, cuprous xanthate is the predominant hydrophobic entity enabling pyrite flotation. Cuprous sulfide and xanthate complexes are easily oxidized in the presence of biopolymers (Mu et al., 2016a). The complexing strength of biopolymers is sufficient to extract the cuprous ions from its sulfide or xanthate ...

The role of sodium metabisulphite in depressing

2019-10-1 · In response to the high pyrite recovery in copper flotation using seawater, this study investigated the role of sodium metabisulphite (MBS), a widely used pyrite depressant, in depressing the flotation of copper-activated pyrite to identify a solution to maximising pyrite rejection.

Pyrite depression in copper flotation

Hi all, i just wanted to find out if there are effective pyrite and insoluble depressants in copper flotation. The situation is that every time we dose a depressant to our stream, we end up ...

A study on the effect of active pyrite on flotation of ...

2018-6-27 · Abstract: Active pyrite is one of the most undesirable phenomena in the flotation of porphyry copper ores. Misreported pyrite into copper concentrates decreased the grade and recovery of copper. In this study, the effective parameters on the flotation process including grinding condition and chemical parameters were evaluated in order to ...
