This communication presented the chlorination-volatilization of cobalt using calcium chloride. Effects of variables on the cobalt volatilization rate were investigated, including the flow rate, oxygen partial pressure, and water vapor content of the carrier gas, the roasting time, and the temperature. It was found that the chlorination of cobalt oxide was mainly in the form of indirect chlorination and cobalt volatilized in the form of gaseous CoCl2.
