Abstract

Procedimento per l'estrazione di metalli, quali zinco, piombo, rame e cadmio da polveri di abbattimento provenienti da forni elettrici per la produzione di acciaio comprendente i seguenti stadi: a) trattamento di dette polveri con una soluzione acquosa di cloruro ammonico e cloruro sodico con solubilizzazione dello zinco, cadmio e rame sotto forma di amminocomplessi, e del piombo sotto forma di clorocomplesso; b) separazione della soluzione così ottenuta dal solido residuo; c) trattamento della soluzione ottenuta in b) con polvere di zinco per precipitare per sostituzione i metalli più nobili dello zinco nella scala elettrochimica; d) separazione della soluzione dal precipitato ottenuto in c); e) estrazione per elettrolisi dello zinco dalla soluzione ottenuta in d) in cella elettrolitica con deposito di zinco al catodo e con svolgimento di ossigeno all'anodo; f) trattamento di nuove polveri di abbattimento da forni elettrici con la soluzione esaurito dallo zinco ottenute in e); g) riciclo del residuo ottenuto in b) al forno elettrico per ridurre l'ossido di ferro e fumigare lo zinco contenuto come ferrite.
