Title:
METHOD FOR PRODUCING NICKEL SULFATE
Document Type and Number:
WIPO Patent Application WO/2024/039055
Kind Code:
A1
Abstract:
A method for producing nickel sulfate, according to exemplary embodiments, may comprise preparing a nickel-containing raw material. A first leachate may be produced by selectively leaching nickel from the nickel-containing raw material by using an oxidizing agent. A second leachate may be produced by separating the residual metals from the first leachate. Subsequently, nickel sulfate may be obtained from the second leachate. Accordingly, unnecessary by-products can be reduced by omitting a separate nickel extraction step.
