Construction and development of a sulphide processing plant began in early 2007 and commissioned in November 2008. During the initial stages of sulphide operation, high copper (Cu)-low zinc (Zn) ore was fed to the plant. Marketable copper concentrate at 91-95% recovery was produced utilizing a high-pH bulk sulphide rougher flotation and 2 ..fier high quality new silicate dust catcher sell at a loss..
Zinc calcine is the soluble zinc form which is the primary feed for the leaching plant. After leaching, the acid leach slurry is thickened and dewatered to recover residues which go to the lead smelter for further processing. After neutralization, clear zinc sulfate solution flows from thickeners to the zinc dust purification circuit.

The processing plant then operates both lead and zinc flotation processes, producing separate concentrates that are filter pressed to produce products containing 5-9% moisture. Silver is also produced and this reports to the lead concentrate. The lead concentrate contains c.73% lead and the zinc concentrate contains c.49% zinc.
The basic steps in this process include (1) preparation of a zinc sulfate solution by leaching zinc oxide calcines (produced by the roasting of sulfide concentrates) in dilute sulfuric acid, (2) purification of the resulting zinc sulfate solution, and (3) electrolysis of the purified solution.
Apr 23, 2016 The problem of treating oxidized lead-zinc ores for the production of high-grade lead zinc flotation concentrates is a complex problem due to the nature of the ores and to the soft sliming characteristics of the lead and zinc minerals. The ore for treatment is a lead-zinc carbonate ore in a mixed siliceous-lime carbonate gangue. The association of the minerals and gangue requires a 65 …
