Abstract

''REGENERAçãO LIVRE DE HIDROGêNIO DE EXTRATORES DITIOFóSFORO METáLICOS'' Este é um método de regenerar ácidos de ditiofósforo a partir de dissulfetos contendo ligações enxofre-enxofre, formadas através da oxidação de ácidos de ditiofósforo, tais como ligações enxofre-enxofre de ácidos ditiofosfórico, ditiofosfónico e ditiofosfínico, em uma fase orgânica de extração por solvente onde p ácido de ditiofósforo é dissolvido em um diluente. Este processo reage o metal diretamente com a solução orgânica contendo o dissulfeto para produzir uma forma complexa metálica carregada do extrator ditiofósforo regenerado na solução orgânica. Esse complexo metálico se forma através da reação direta do metal com os dissulfetos sem requerer a presença ou a formação do hidrogênio nascente ou gasoso. A solução orgânica contendo o extrator ditiofósforo regenerado pode ser igualmente diretamente reciclada para dentro de um circuito de extração por solvente ou reciclada após o metal carregado ser extraído.
