Abstract

Inventia se refera la un procedeu de separare a pulberii de platina-rodiu din site catalizatoare uzate. Procedeul consta în dizolvarea sitei uzate, conversia la cloruri, separarea metalelor comune, reducerea platinei-rodiului, filtrarea precipitatului, spalare, uscare si cîntarire, obtinîndu-se pulbere metalica de platina-rodiu, de culoare cenusie, de înalta puritate.
