  • Solvent Extraction and Separation of Copper and Zinc from

    Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid and Cyanex 272 separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. It was observed that copper was almost completely extracted into the organic phase

    Such oxide ores are usually leached by sulfuric acid, usually in a heap leaching or dump leaching process to liberate the copper minerals into a solution of sulfuric acid laden with copper sulfate in solution. The copper sulfate solution (the pregnant leach solution) is then stripped of copper via a solvent extraction and electrowinning plant

    As with oxide ores, solvent extraction and electrowinning technologies are used to recover the copper from the pregnant leach solution. Supergene sulfide ores rich in native copper minerals are refractory to treatment with sulfuric acid leaching on all practicable time scales, and the dense metal particles do not react with froth flotation media.

    The liquid percolates through the stockpile and dissolves copper minerals, producing an approx. 60% copper concentration called pregnant leach solution (PLS). The PLS then flows to a collection reservoir and to the solvent extraction plant; the copper is then transferred from the mildly acid aqueous leach solution to an organic solution.

    An organic solvent specific to the extraction of copper is applied to the weak acid, or pregnant liquor. The copper moves into the organic phase, leaving its impurities in the leach solution. The copper ions are exchanged for hydrogen ions, so the aqueous phase can be recycled while a strong acid solution is introduced to the organic phase.
