Study of New Process for Recovery of Cobalt Oxide from Al-containing Cobalt Sulphate Solution AITranslate
Abstract AITranslate
Study is made of a new process for directly extraction of the cobalt oxalate from ammonium oxalate in the acid solution directly dissolved from lithium cobaltate. Aluminum in the acid solution is completely complexed with F salt. Then,cobalt is precipitated with ammonium oxalate at pH= 2 and under 60 ℃. Finally,the cobalt is calcined into cobalt oxide in the muffle. To obtain the product,which is up to the requirement of the Co2O3-Y1（ehinese code GB6518-86）. The dosage of the F salt is 110% of the theoretic dosage; while the dosage of ammonium oxalate can be reduced by 50 %. The rate of cobalt precipitation with ammonium oxalate is 99.37%.
