Abstract
"MéTODO DE REMOçãO DE IMPUREZAS DE CONCENTRADO DE OURO CONTENDO SULFETOS". A presente invenção se refere a um método para remoção de impurezas, como telúrio e bismuto, de concentrados de ouro contendo sulfetos. De acordo com o presente método, as impurezas são lixiviadas do concentrado de ouro com a ajuda de uma solução acídica aquosa, sob elevada temperatura, pelo que as impurezas se dissolvem e o ouro permanece no concentrado.
