<p>The invention relates to a method for disposing of run-down batteries and other, mainly metallic, waste products made toxic by the presence of heavy metals. During an initial stage of the method, run-down batteries and the toxic compounds are introduced into a molten iron bath wherein, under a reducing medium, the metallic compounds are reduced to the metal state, and in this condition, partly dissolved through the molten iron and partly vaporized; the stable metallic compounds under reducing medium are instead absorbed to a slag generated by feeding a suitable scorifier into the molten iron bath.</p> |
