Upgrading of Co and Its Separation from Impurities in Weakly Co-containing Solution AITranslate
Abstract AITranslate
Study is made on the upgrading of Co from low-grade concentrate calcine leachateand its separation from impurities. The studied leachate is free of Fe and Cu, with Co contentonly about 1 g/L while the impurities such as Mg. an. Ni. Mn. St etc in it are about ten times asmuch as Cab. After absorption by absorbent and then processing by HCl at room temperature, thecontent of Co in Hcf solution is about 13 g/L, and Co in the effluent is less than 1 mg/L. Afterevaporating and concentration. Co could be upgraded to over 20 g/L in the enriched solution andseparated from Si. The total recovery of Co to rich Co solution could reach as much as 98. 7%.Then extracted by N235 to separate impuritys CoC12 could reach the technical-purity standard.
