Flotation of zinc oxide ores by cationic and mixed ...
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 (Pereira ...
A review of zinc oxide mineral beneficiation using ...
The flotation of zinc oxide minerals is suggested for sulfidization of the smithsonite followed by activation with CuSO 4 and flotation of the activated zinc oxide using xanthate at pH 10.5 . It is also implied that after pretreatment of the pulp with sulfidizer followed by reconditioning with CuSO 4 , zinc oxide flotation can be achieved with a mixture of xanthate/mercaptan collectors [6] .

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.

Concentration of zinc oxide ores by froth flotation …
Froth flotation for zinc oxides allows us to separate zinc bearing minerals from gangue, also from lead, copper, and others. The usual grade of zinc in oxides ores is between 2% and 10% of Zn. After flotation concentrates contain 40-50% Zn. The concentrate of zinc obtained after flotation and dewatering remains in the form of oxide.
How to Process Oxidized Lead-Zinc Ore by Flotation
The combined products flow to a zinc conditioner where soda ash, sodium silicate and an organic colloid are added to disperse the pulp and complex the slimes which might interfere with flotation. The additional reagents required for the zinc flotation consist of sodium sulphide, primary amines and a frother which are added to the conditioner discharge in the order stated and prior to entering ...
