Abstract

The extraction of Nickel from electrolytic solutions of copper and cobalt treated at the hydromet talurgical plants of SHITURU, using DUOLITE resin C20, was carried out according to two loadings of this specific nickel resin: the loading in bach and the loading in column.

The maximum bachloading of the nickel resin was carried out at a pH of 2.5 for 6 hours, thus leading to a recovery efficiency of nickel of about 98%. As for columnload ing, the evolution of time shows that at a pH of 2, for 8 hours, the recovery of is appreciable with a yield which is close to 95%.
