Abstract

"PROCESSO PARA TRATAMENTO DE UM MATERIAL CONTENDO PELO MENOS UM óXIDO DE METAL BASE". é revelado um processo para lixiviação de um metal precioso de materiais óxidos, tais como, minério de níquel laterítico, compreendendo a etapa de lixiviação do minério com um lixiviador compreendendo um sal catiónico (por exemplo, cloreto de magnésio) e ácido clorídrico. Pode ser adicionado um oxidante ou cloreto de metal adicional (tal como aquele que resulta da operação de lixiviação). Em uma concretização, o processo compreende a recuperação do metal precioso de minério compreendendo as etapas de: lixiviação do minério com um lixiviador; separação de um lixiviado rico em metal precioso do minério em uma primeira separação sólido-líquido; oxidação e neutralização do lixiviado rico em metal precioso assim obtido; e separação de uma solução de cloreto de magnésio do lixiviado assim obtido, em uma segunda separação de sólido-líquido. Em outra concretização, a solução de lixiviador é regenerada da solução de cloreto de magnésio. Em uma concretização adicional, a regeneração da solução de lixiviador inclui a etapa de produção de óxido de magnésio a partir da solução de cloreto de magnésio.
