Abstract

"RECUPERAçãO DE VALORES DE NìQUEL E COBALTO DE UM CONCENTRADO DE FLOTAçãO SULFìDICO POR LIXIVIAçãO SOB PRESSãO OXIDATIVA AUXILIADA POR CLORETO EM áCIDO SULFúRICO". Apresenta-se um processo para a recuperação de valores de níquel e cobalto de um concentrado de flotação sulfídico. O processo envolve a formação de uma pasta semifluida do concentrado de flotação em uma solução de ácido sulfúrico, e submissão do concentrado de flotação na pasta semifluida a uma lixiviação com cloro a pressão atmosférica, seguida por uma lixiviação sob pressão oxidativa a temperatura elevada, sob condições ácidas. Após a separação de líquido-sólido, purificação e remoção do cobalto, a solução contendo níquel é diretamente tratada por recuperação por eletrólise, para recuperar catodo de níquel dela.
