Lithium system for precipitation of metals and regeneration of oxidants for leaching solution of metals, slags, metal sulfides and sulfide minerals, the metal content of which comes from the solution of leaching solution, including one-stage precipitation and oxygenation process, Delete the stage of filtering, washing, transportation and treatment of highly toxic reagents

摘要

It is used to precipitate different kinds of metals (copper, zinc, nickel, cadmium, cobalt, silver, gold) from the leach solution in the environment of sulfur oxidizer or hydrogen chloride oxidizer and the unified lithium system of the leach solution of regenerated metal sulfide, Including processes that can unify the existing reduction processes, followed by complex and potentially environmentally dangerous oxidation processes, so as to avoid dangerous transportation, loading and unloading operations, storage and treatment of toxic substances, And reduce environmental pollution residues,Obtain a commercial grade catodico product and a solution that can be reused in the leach process. The system includes a membrane device (3) which is composed of one or more oxidant tanks (7) and connected with valves.There is one or more anodica solution pools (6) and one or more catadica solution pools (2),The membrane device (3) is composed of one or more cathode parts (4) and one or more anode parts (5), wherein each or more anode parts (4) are separated by a selective unidirectional ionospheric exchange membrane.
