Abstract
MéTODO PARA A RECUPERAçãO DE OURO A PARTIR DE UMA SOLUçãO CONTENDO OURO. A invenção se refere a um método para a recuperação de ouro a partir de uma solução de cloreto contendo ouro usando-se carbono ativado. A solução de cloreto contendo ouro e o carbono são contactados uma com o outro, após o qual o ouro que se formou como partículas metálicas na superfície do carbono é separado a partir do carbono usando-se métodos físicos como concentrado de ouro que contém ouro metálico.
