The effects of grinding fineness, amount of Na2CO3, amount of Na2SiO3, amount of Na2S and amount of octadecylamine were investigated, respectively.

Mechanism study on the sulfidation of ZnO with sulfur and ...

At the present, zinc is produced mostly from zinc sulphide ores because the sulphides are easy to separate from the gangue by conventional flotation techniques. In the case of oxide zinc ores, there is often no selectivity in terms of zinc recovery. The objective of the present study is to investigate the influence of different cationic ...

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 …

Silver Lead Zinc Ore Processing Method using Flotation

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.

Mechanism study on the sulfidation of ZnO with sulfur and ...

The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and iron content, and the benefits compared to traditional technologies are shown.
