Flotation of zinc oxide ores by cationic and mixed

Oct 01, 2012· 1. Introduction. The flotation of oxidized Pb and Zn minerals, particularly Zn minerals, is much more difficult than the flotation of corresponding sulfide minerals (Hosseini and Forssberg, 2007).The most common flotation technique used commercially for the treatment of ZnO minerals is sulfidization with Na 2 S, followed by treatment with conventional cationic collectors, namely amine

FLOTATION OF ZINC OXIDE ORE USING CATIONIC AND

Flotation of zinc oxide ore using cationic and cationic-anionic mixed collectors 151 Armac C. The increase of both collectors dosage increases Zn recovery and decreases Zn grade in the smithsonite flotation concentrate. The reduction of Zn grade is at-tributed to the flotation of more gangue minerals due to high collector concentration. Fig. 6.
