Abstract
It is possible to dissociate samples of zinc oxide at high temperature by using a concentrated radiation as a best source. However, the reoxidation radiation between the products is very fast and it is hence necessary to cool down very rapidly (quench) the gases. The present paper describes two experimental methods of analysis owned at measuring the quench efficiency (i.e. the fraction of zinc recovered). The accuracy of both methods is first presented. Then, preliminary results obtained in an image furnace are given. It is concluded that it is necessary to optimize the quench reactor in order to enhance to efficiency of zinc production.
