INTEGRATED INNOVATIVE METALLURGICAL SYSTEM TO …

Currently there is no economical and viable process for on-site metal extraction from Low Grade, Complex or Poly-metallic deposits mainly Cu, Pb & Zn. Traditionally, metals recovery from polymetallic sulfide deposits is performed by mining, selective flotation to separate Cu, Pb and Zn concentrates, and finally, smelting/refining

    This process is used for the of copper from sulfide . In this process, the crushed and ground in bulk about 100,000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.

Low-grade ores are eco-nomically viable only in the presence of a feasible application of physical and chemical geotechnologies, such as heap leaching. Ores of the oxidation zone of the Malmyzh deposit typically have a copper content less than 0.3% and a 0.1–1.2 ppm gold content.
