| Abstract: | The process of purification and impurities removal and preparing cobalt oxide and tricobalt tetroxide by strip-ping liquor of cobalt produced from ocean polymetallic nodules by smelting-rusting-solvent extraction process was stud-ied. The results show that the purification and impurities removal process has advantages of easier operation, lower con-sumption of auxiliary agents, high recovery of cobalt, and is applicable and profitable in commercial production. The prepared cobalt oxide is up to the national standard. |
