Abstract
In this study, recovering of zinc ions in the residual solution occurring after copper cementation by zinc metal was investigated. The zinc ions in the solution were recovered by using sodium bicarbonate as precipitation agent. After the precipitated product was separated from the solution, it was dried at 80°C for 5 h in an oven and was subjected to the calcination process to obtain zinc oxide. The XRD and SEM analyses of the precipitated and calcined products were carried out. It was determined that the precipitated solid was Zn5(CO3)2(OH)6 (hydrozincite) and the calcined product was ZnO.
