Title:

METHOD FOR RECOVERING NICKEL HYDROXIDE AND NICKEL SULFATE FROM NICKEL-CONTAINING MATERIALS

Document Type and Number:

WIPO Patent Application WO/2024/076100

Kind Code:

A1

Abstract:

The present invention provides a method for recovering nickel hydroxide and nickel sulfate from nickel-containing materials, wherein the nickel-containing materials are crushed and pulverized and then leached with sulfuric acid, leached residue separation and filtrate separation are performed and then the pH is adjusted to recover nickel hydroxide, and the recovered nickel hydroxide is further subjected to a sulfation reaction to recover nickel sulfate.
