<p>An apparatus for the recovery of metallic materials is characterised in that it is frustoconical, and consists of a metallic casing (2) internally lined by a refractory coating (3), the reactor being rotated about its vertically arranged geometrical axis (1) and being fitted with a drain hole (5) in its base for discharging liquid charge whilst solid charge, due to the effect of the several forces in play, adheres to the walls of the reactor. <IMAGE></p> |
