Abstract

"MéTODO PARA EXTRAçãO DE LIXìVIA DE MINéRIOS CONTENDO MINERAIS E CONCENTRADOS E MéTODO PARA EXTRAçãO DE LIXìVIA DE MINéRIOS DE CALCOCITA CONTENDO PIRITAS RELATIVAMENTE BAIXAS". Prevê um método para extração de lixívia de minérios de cobre/ferro/enxofre e concentrados incluindo a lixiviação do mineral com um fluxo aquoso contendo íons férricos e ácido sulfúrico na presença de oxigênio, em que o fluxo aquoso inclua uma solução formada pela reação de sulfato férrico básico com excesso de ácido sulfúrico; métodos integrados de formação e relixiviação de sulfato férrico básico também são descritos.
