Lead Zinc Ores Beneficiation- The Common Used Methods

Usually, we apply the jigging method to concentrate lead minerals (after grinding at 10mm or less). Shaking tables are also useful for both lead and zinc, but mostly after flotation. The gravity concentration of lead could result in a 10% Pb product, sometimes up to 30% and 60%, depending on the feed grade and the liberation size of lead

Effect of grinding media on zinc depression in a lead

Aug 01, 2009· Unfortunately, with the possible exception of the iron sulphate tests, none of these methods managed to improve galena/sphalerite selectivity when grinding with high chrome grinding media, and restore the lead grade/recovery curve to the same position as that observed for forged media (see Fig. 2).The iron sulphate tests indicated a more electrochemically active grinding media would

Influence of the Addition of Depressants during Grinding

The flotation performance of a complex lead and zinc ore were investigated by changing the grinding environments. Four groups of testing were conducted with different depressants or their combinations. Flotation results, size-by-size analysis, pulp potential (Eh) and dissolved oxygen (D0) were studied. It was found that the addition of depressants during grinding was beneficial to increasing

Zinc smelting Wikipedia

Zinc smelting is the process of converting zinc concentrates (ores that contain zinc) into pure zinc. Zinc smelting has historically been more difficult than the smelting of other metals, e.g. iron, because in contrast, zinc has a low boiling point.At temperatures typically used for smelting metals, zinc is a gas that will escape from a furnace with the flue gas and be lost, unless specific
