Abstract

Procédé chimique par voie humide permettant l'obtention d'or et d'argent par la désagrégation directe sulfurique oxydante de concentrés d'arsénopyrite (FeAsS2) carbonés avec de la gangue silicatée ou de la gangue silicatée ou pyrtitique, dans lequel de l'arsenic et du fer sont entièrement convertis en solution et les métaux précieux sont enrichis quantitativement dans le résidu silicaté. Après décarbonisation du résidu, il est possible d'obtenir de l'or et de l'argent par lessivage au cyanure sans pertes d'adsorption. Est également décrit un procédé chimique par voie humide pour fabriquer des concentrés à haute teneur en or et en argent.
