Flotation of zinc oxide ores by cationic and mixed collectors

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

Flotation of Aladagˇ oxide lead–zinc ores ScienceDirect

The scope of this study was to recover oxide lead and zinc minerals from Aladağ Region (Kayseri-Turkey) ores. Primary studies carried out with this ore have shown that flotation of oxidized lead and zinc minerals, in particular zinc minerals was difficult (Engin and Önal, 2003). In this paper, flotation properties of lead–zinc minerals or

Sulphidization flotation for recovery of lead and zinc

Investigators originally reported that for the zinc oxide flotation circuit, the best results are at pH levels between 10.5 and 11.5, although some ores respond well to the process at lower pH levels.

Flotation of Lead and Zinc Froth Flotation (Sulphide

Froth Flotation (Sulphide & Oxide) Froth Flotation The separation is done via pH control while zinc sphalerite is still inactive. Once the Pb is removed, the addition of copper sulphate will activate the zinc and allow you to float it (at a higher pH). Your situation may vary a little but here is an example.

How to Process Low-Grade Lead Zinc Ore by Flotation

The zinc tailings pass over a Wilfley Table which gives the operator a constant, visual picture of the efficiency of the zinc flotation machine, and also recovers additional zinc values. Zinc concentrates are fed to a Wilfley Table to remove any lead oxide values which may have floated with the zinc, and then are thickened in a Thickener.
