<p>The method for dechlorinating and oxidizing secondary zinc starting-materials comprises charging the chlorine-containing zinc starting-material to a reactor (1) and heating to 750 DEG C by means of a hot gas (4) charged to the reactor, such as to vapourize the zinc chloride, whereafter the gaseous zinc chloride is withdrawn through an outlet (6) located at the top (7) of the reactor, and a dechlorinated zinc and zinc-oxide product is withdrawn from the reactor (1) at a lower level (at 5) thereof. <IMAGE></p> |
