Abstract
"PROCESSOS DE TRATAMENTO, DE RECUPERAçãO DE VALORES METáLICOS E DE PRODUçãO DE áCIDO SULFúRICO E RECUPERAçãO DE METAIS PRECIOSOS". A presente invenção diz respeito no geral a um processo para a produção de ácido sulfúrico e liberação de valores de metal precioso a partir de materiais contendo enxofre através de operações de lixiviação sob pressão. De acordo com os vários aspectos da presente invenção, os materiais que carregam enxofre podem compreender resíduos de operações de lixiviação sob pressão, tais como aquelas realizadas em temperaturas moderadas. O processo da presente invenção pode ser vantajosamente usado para converter tais materiais que carregam enxofre ao ácido sulfúrico por meio de lixiviação sob pressão. O ácido sulfúrico assim produzido pode ser beneficamente usado em outras operações de processamento mineral, por exemplo, aquelas no local onde ele é produzido. Os metais, tais como metais preciosos, que estão contidos dentro dos materiais que carregam enxofre podem ser vantajosamente recuperados dos produtos de processamento pela tecnologia de recuperação de metais preciosos estabelecida.
