Abrégé
(PT)
PROCESSO PARA DIGESTÃO ÁCIDA DE COMPOSTOS CONTENDO METAL, E, MEIO AQUOSO DE LIXIVIAÇÃO A presente invenção refere-se a um processo para digestão ácida de compostos contendo metal por lixiviação com meio aquoso de lixiviação contendo i) um ácido alcanossulfônico e, se apropriado, ácido sulfúrico e/ou tensoativo e/ou ii) uma mistura de um sal de ácido alcanossulfônico com ácido sulfúrico bem como, se apropriado, tensoativo. É também objeto desta invenção um meio aquoso de lixiviação contendo um ou mais ácidos alcanossulfônicos e, se apropriado, ácido sulfúrico e/ou um tensoativo, bem como um meio aquoso de lixiviação contendo um ou mais sais de ácidos alcanossulfônicos, ácido sulfúrico e, se apropriado, um tensoativo.
