Abstract

"PROCESSO PARA O TRATAMENTO DE CONCENTRADO DE MOLIBDêNIO". A presente invenção refere-se a um método de tratamento ou purificação de um concentrado de molibdênio também contendo cobre, compreende a etapa de submeter o concentrado de molibdênio à oxidação por pressão na presença de oxigênio e uma solução de alimentação contendo cobre (por exemplo, CUS0 ~4 ~) e haleto (por exemplo, CUCI~ 2~) para produzir uma solução de oxidação por pressão contendo cobre e um resíduo sólido contendo molibdênio. A solução de oxidação por pressão pode ser combinada com solução de alimentação para uma segunda oxidação por pressão onde um concentrado de cobre é tratado para a recuperação de cobre do mesmo.
