Flotation of zinc oxide ores by cationic and mixed ...

01-10-2012  In Dandy processing plant, Zanjan, Iran, the tailing of cerrusite flotation is Zn concentrate containing 20–25% Zn which is leached by sulfuric acid to extract the Zn metal. In recent years, by decreasing the Zn content of the ore, the upgrade of tailing by froth flotation before acid leaching has become considerably attractive.

FLOTATION OF ZINC OXIDE ORE USING CATIONIC AND CATIONIC ...

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.

Physicochemical studies of oxide zinc mineral flotation

The studies on oxide zinc ore indicate a maximum bench scale flotation recovery of 84.5 % with zinc grade 24.5% in the presence of dodecylamine at pH 11.5. There are no significant variations in recovery of cationic and anionic and mixed collectors, however, amine and mixed collector flotation show to be more selective than anionic collectors.
