Abstract

Patente de Invenção:<B>"PRECIPITAçãO SELETIVA DE NìQUEL E COBALTO"<D>. Método de precipitação de níquel e cobalto a partir de uma solução ácida aquosa contendo pelo menos níquel, cobalto e manganês dissolvidos, o método incluindo: adição de óxido de magnésio calcinado cáustico sólido ou óxido de magnésio calcinado cáustico recentemente transformado em pasta fluida à solução, o óxido de magnésio sendo adicionado em uma quantidade suficiente para precipitar uma proporção substancial de níquel e cobalto em solução e precipitar uma proporção menor de manganês na solução; manutenção do óxido de magnésio em contato com a solução durante um período de cerca de 1 hora a cerca de 9 horas a fim de, dessa forma, obter a precipitação de uma proporção substancial de níquel e cobalto em solução e a precipitação de uma proporção menor de manganês em solução; e separação dos sólidos precipitados na etapa (b) acima da solução aquosa. De preferência, cerca de 80% a 100% de Ni e Co em solução são precipitados e cerca de 5% a 15% do Mn em solução são precipitados. O material precipitado se separa precocemente da solução. O precipitado contém baixos níveis de Mn e Mg e ainda pode ser tratado a fim de recuperar níquel e cobalto.
