Abstract
Metodo per il recupero dei metalli da materiali che li contengono sotto forma di solfuri e che comprende le fasi di lisciviazione di detti materiali con una soluzione ad alta concentrazione di ioni cloruri e di ioni ammonio ed in presenza di sali di rame, di trattamento della soluzione ottenuta con ammoniaca per precipitare ossicloruro di piombo, di trasformazione dell'ossicloruro di piombo in carbonato, di precipitazione di ossicloruro di rame per ossidazione ed ebollizione della soluzione e di recupero dello zinco dalle soluzioni.
