Centrifugal extraction machine high nickel matte sulfuric acid selective leaching experiments compared with sulfide nickel anode refining process, high nickel matte sulfuric acid selective leaching - Bioleaching has short process and equipment investment of the province, the advantages of low production cost. The basic process of the process is: after the fine grinding of high nickel matte USES the normal pressure leaching and pressure leaching of the method of combining segments leaching, nickel and cobalt were selective leaching, into the solution, copper, iron, such as precious metals is suppressed in the leach residue. Leach liquor purification treatment, using the method of insoluble anode electricity production of electroless nickel deposition, or hydrogen reduction process production of nickel powder. 1 -
