Process of leaching of Copper sulfide concentrates of tetra hidritico containing Arsenic and antimony in high concentrations.

摘要

Process of leaching of Copper sulfide Concentrate type tetrahedritico containing Arsenic and antimony in high concentrations.In re Pulping consisting of an aqueous solution of ferrous sulfate to a Solid liquid ratio fixed and controlled then undergoes an oxidation reaction with a gas containing Oxygen in an agitated reactor pressure and high temperature, Rusting sulfides to sulfates And precipitating Iron and antimony in the form of FERRIC ARSENATE.Forming a Pulp leaching in the solid phase usually contains Iron, antimony and Arsenic, as well as the insoluble sulfates of non-ferrous Metals and Noble Metals, such as Lead, and the liquid Phase contains Copper, sulfuric acid and Sulfate Free, put in as much of the S soluble non-ferrous metal, such as zinc, cadmium, Cobalt.All the metals are recovered by Cementation of Copper Scrap hierrodel Liquid leaching.
