Physicochemical studies of oxide zinc mineral flotation

At the present, zinc is produced mostly from zinc sulphide ores because the sulphides are easy to separate from the gangue and to concentrate by conventional flotation techniques but in the case of oxide zinc ores, the recovery of zinc is not enough high.

Extraction of Zinc | Application Of Zinc Refining Process

Historically extraction of zinc has been more difficult than extraction of other metals because at temperatures where metals such as iron typically begins to melt, zinc is a gas. Due to its very low boiling point, at such temperatures, zinc will escape with exhaust gases.

Influence of important factors on flotation of zinc oxide ...

The effect of slime on oxide flotation is strong and the reason is complicated. The feed to the oxide zinc flotation circuit requires careful desliming prior to flotation, which is then performed with a relatively large amount of sulphidizing agent and a cationic collector, with frother added as required (Hosseini and Forssberg, 2006c).

flotation of zinc oxide ore

The separation of metallic zinc from its ores by pyrometallurgy is much more difficult than with other common metals, such as copper, lead, and iron, because the reduction of zinc oxide by carbon (C) proceeds spontaneously only above the zinc boiling point of 907 °C (1,665 °F).
