Abstract

La présente invention concerne un système de récupération d'or, le composant d'un minerai d'or présent dans des déchets en vrac étant retiré par flottation par moussage et le concentré résultant étant ensuite traité selon des procédures classiques de lixiviation au cyanure. L'invention est caractérisée en ce que 96 - 98 % d'or provenant du minerai sont finalement récupérés, le système comportant les étapes suivantes : a) concassage et broyage du minerais; b) séparation du sable de la boue primaire; c) traitement de ladite boue primaire avec un collecteur sulfhydrique; d) broyage secondaire dudit sable, et séparation de la boue secondaire du sable; e) traitement de ladite boue secondaire avec un collecteur sulfhydrique - d'acides gras; f) traitement dudit sable avec le collecteur sulfhydrique - d'acides gras; g) collecte des concentrés issus de (3), (5) et (6), et séparation du sable desdits concentrés (à 20 - 30 μ); h) traitement dudit concentré avec du cyanure; i) passage d'un contre-courant de charbon actif dans le flux du concentré; j) séparation des rejets et résidus issus du charbon chargé; k) traitement du carbone chargé avec du cyanure chaud et une solution caustique; et I) extraction par voie électrolytique de la liqueur et fusion de l'or en lingots.
