The chlorination process utilizing ammonium chloride as chlorination reagent has been employed for the recovery of elements with emphasis on indium from bearing alloy through vaporization of the chlorides. It was found that the chlorination took place by the heating of the model sample in the presence of ammonium chloride. The influence of the process parameters, such as reaction temperature and gas flow rate, has been investigated. The addition of activated carbon resulted in the adsorption of chloride on the carbon surface. The present result indicates the possibility of the recovery process through transport of the target element from the sample to pores of activated carbon.
