Document Type and Number:
WIPO Patent Application WO/2018/077241
Kind Code:
A1
Abstract:
A method for treating iron-removed and aluminum-removed liquid. The iron-removed and aluminum-removed liquid in the method comprises nickel chloride and cobalt chloride. The method comprises: (1) mixing iron-removed and aluminum-removed liquid and a first calcium hydroxide solution to obtain nickel and cobalt deposited pulp; (2) performing thickening treatment on the nickel and cobalt deposited pulp to obtain nickel and cobalt deposited overflow and nickel and cobalt deposited thick pulp, and performing filter pressing on one part of the nickel and cobalt deposited thick pulp to obtain a nickel cobalt hydroxide filter cake; and (3) mixing the other part of the nickel and cobalt deposited thick pulp and second calcium hydroxide to obtain mixed pulp, and returning to the step (1) to mix the mixed pulp, which substitutes the first calcium hydroxide solution, and the iron-removed and aluminum-removed liquid.
