Following the full production of Lygend OBI Island HPAL Project Phase I on October 24, 2021, the stand-alone test run and commissioning test run of the nickel-cobalt hydroxide CCD washing process were successfully completed on December 19, 2021, completing an important step in elevating the HPAL Project from "products" to "competitive products".
The nickel-cobalt hydroxide CCD washing process is to wash nickel-cobalt hydroxide through a thickener against current, which can greatly reduce the contents of impurities such as magnesium sulfate and sodium sulfate in nickel-cobalt hydroxide products, thereby greatly increasing the nickel-cobalt content of the product. This process will further improve the quality of MHP's finished products, provide customers with higher-quality products, and strongly guarantee the supply of raw materials for the development of new energy industry.
This Sub-project was constructed by China National Chemical Engineering Sixth Construction Co., Ltd., and cooperating fully with the Lygend proprietor, jointly promoted the successful operation of the nickel-cobalt hydroxide CCD washing process project.
