A satisfactory separation of chalcopyrite and pyrite was achieved at weakly alkaline condition (pH 8), at which the flotation recovery of chalcopyrite was % and that of pyrite was only %. The results of surface analyses confirmed that GM could be selectively chemisorbed on pyrite surface through the Fe sites and impede the further ...

Floatation of Ok Tedi Pyrite

Floatation of Ok Tedi Pyrite

+

Pyrite is a significant gangue sulphide mineral in the Ok Tedi copper ore. Its presence in the flotation concentrate is not entirely desirable since it lowers the grade of the final copper concentrate. Lime depression of the pyrite has been practiced with some success. However, it has been observed that at the pH for pyrite depression a significant amount of the pyrite particles still float.

the maximum pyrite recovery being obtained at 35 mV (SHE) at pH 9. Cyanide may reduce the flotation pulp potential and inhibit the electrochemical activity on pyrite surface which is however essential for the action of copper activation. Therefore, the use of cupric ion as an activator for pyrite flotation in the presence of cyanide

Jan 28, 2021 · Pyrite flotation separation and encapsulation in tailings dams is proposed as a viable way to chemically stabilize tailings. Characterization of potential acid mine generation in tailings led to an innovative process in which acidgenerating pyrite is separated by flotation from the coarse tailings and incorporated into the slime zone. This creates pyritefree neutral tailings acceptable for ...

Feb 08, 2007 · Comparison of flotation selectivity and washahilitv curves showed that entrainment of fines due to water flow was the reason for the loss of selectivity during flotation of coal from nonpyritic minerals. In the ease of pyrite, in audition to entrainment. flotation of pyrite due to its natural hydrophobicity contributed to the loss of selectivity.
