Abstract. Stoichiometric mixtures of ZnS + Al and ZnS + Mg were milled for different times in a planetary ball mill. The XRD traces of the as-milled samples showed the presence of zinc, MgZn 2, and MgS after 30-min milling in the ZnS–Mg system.The traces of MgZn 2 disappeared after 1-h milling and the reduction reaction seemed to have been completed after 5-h milling.
