processing zinc ore

Lead

The established leadzinc ore flotation processing scheme is to add zinc sulphate (ZnSO4) to the grind to control metal ion activation (sphalerite depression). Often metabisulphide or other sulphidation chemicals are added with the zinc sulphate for iron sulphide mineral depression.

The processing of zinc silicate ores— A review

Previous processes, both pyrometallurgical and hydrometallurgical, for treating zinc silicate ores are reviewed. Some comparisons are made with the new continuous leaching process recently developed by the Electrolytic Zinc Company of Australasia Limited. These comparisons, based on tests with two different zinc silicate ores, demonstrate the simplicity and effectiveness of the new process.

processing cost of zinc ore

Zinc. The traditional approach to processing zinc, known as the roastleachelectrowin (RLE) process has long been used to effectively process sulphide ores, but has limitations when it comes to more complex sulphide ores, and is not capable of processing other ore types. Additionally, the RLE approach produces SO2 gas, which requires fixation.
