| Abstract Scope |
Sumitomo Metal Mining, Co, Ltd. (SMM) has a globally unique and original model based on collaboration among three businesses of the mineral resources , smelting and refining, and materials.
It can provide a comprehensive in-house nickel supply chain covering everything from securing nickel mineral ore raw material to the production of battery materials for EVs. Niihama Nickel Refinery , own by SMM has a variety of process including solvent extraction which is main process for producing nickel sulfate used for battery materials.
This solvent extraction process, which is called "Crowding organic bypass - solvent extraction (COB-SX)", is unique and effective for not only nickel and cobalt separation, but also nickel and other impurities. This report shows some improvements about mainly solvent extraction process such as removal of impurities and separation of organic and aqueous phase. |
