A review of zinc oxide mineral beneficiation using

A review of zinc oxide mineral beneficiation using

In recent years, extraction of zinc from low-grade mining tailings of oxidized zinc has been a matter of discussion. This is a material which can be processed by flotation and acid-leaching methods. Owing to the similarities in the physicochemical and surface chemistry of the constituent minerals, separation of zinc oxide minerals from their gangues by flotation is an extremely complex process

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

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

Nevertheless, whether sulfidation-xanthate flotation or sulfidation-amination flotation, surface sulfidation of the mineral is an important prerequisite for flotation of zinc-oxide minerals. However, in contrast to other metal oxide minerals, it is extremely difficult to realize the sulfidation of zinc-oxide minerals ( Lan et al., 2020 ), and
