Abstract

L'invention concerne un procédé de récupération d'or d'un concentré, tel qu'une boue électrolytique, un précipité zinc-or, des déchets globaux d'or et un concentré obtenu par gravité. Ce concentré est lessivé dans une solution HCl à base de chlore gazeux afin de dissoudre l'or. Les métaux de base et l'or sont ensuite précipités à partir d'une solution extraite d'une bouille produite au moyen du procédé de lessivage. Le chlore est produit sur site si le contenu en or de la bouille est > 1 %, alors que le gaz en bouteille est utilisé si le contenu en or est > 10 %.
