ABSTRACT

The influence of different parameters (duration, temperature, zinc dust quantity, concentration of activators - copper and antimony) on the process of activated cementation of Co and Ni has been studied. Industrial zinc sulfate solutions have been used. During the process of activated cementation of Co and Ni, copper (involved as CuSO4.5H2O) and antimony (involved as KSbC4H2O6.1.5H2O) were used as activators. The results obtained will be used to establish optimal conditions for the carrying out of cobalt and nickel activated cementation in the Zinc Production Plant in KCM SA, Plovdiv. Keywords: Activated Cementation, Cobalt, Nickel, Antimony.
