Bioleaching solvent extraction procedures and with Selective Recovery of copper and Zinc from polymetallic sulfide concentrates

摘要

The biofiltration and extraction process of solvents for selective recovery of copper and zinc from polymetallic sulphide concentrate, including a stage of organic synthesis and reduction of organic ions, followed by a stage of copper and zinc solvent extraction, in which biofiltration and reduction Ion enrichment includes the solid phase of polymetallic sulfide C separated from the polymetallic sulfide B biological concentrate Octopus C and the preparation phase of the octopus produced from the biological phase, andD-ion reduction conversion, while the solvent extraction stage of copper and zinc includes the solvent extraction of copper and the electrolytic stage B arsenic control and, C. solvent and electrolytic extraction of zinc, where the biodegradation stage is through the use of multiple types of biological antibiotics agitation tank, with an air jet and diffusion system, which can handle more than 15 solid pulse density, high air distribution efficiency, In addition to the water evaporated during the recovery process
