Abstract

Procedimento per la prevenzione dell'esaurimento dei bagni acidi di ramatura (12) e per il trattamento dei liquami o fanghi (20) contenenti rame in forma ionica allo scopo di recuperare il rame metallico (39), prevedendo l'aggiunta (11) di un composto che mantiene la concentrazione di ferro al di sotto di un valore critico (ad esempio 60 g/l), detto composto facendo precipitare il ferro sotto forma di solfato ferroso impedendo così la co-deposizione di cristalli di solfato ferroso e di solfato di rame, con eventuale inglobamento di impurità organiche quali gli stearati (35) presenti nei detti bagni acidi di ramatura.
