Abstract
MéTODO PARA RECUPERAçãO DE OURO A presente invenção refere-se a um método para recuperação de ouro de um produto intermediário ou resíduo de lixívia contendo enxofre e ferro gerados na lixiviação de uma matéria-prima sulfídica. A recuperação de ouro e de outros metais valiosos da matéria-prima sulfídica ocorre em uma atmosfera de cloreto. O ouro ontido no produto intermediário ou resíduo é lixiviado com cobre divalente e cloro em uma solução de cloreto de cobre (II)/ cloreto de sódio, em condições nas quais o potencial de oxi-redução se situa no intervalo de 650-750 mV e o pH entre 1,0 e 1,6. O ácido gerado durante a alimentação de cloro é neutralizado com um álcali adequado. A neutralização evita os custos de dissolução do ferro.
