Abstract

L'invention appartient au domaine d'enrichissement de la masse rocheuse de gisements alluviaux, métallifères ou ayant des origines industrielles, et permet d'extraire des métaux libres, y compris des métaux fins et minces tels que l'or ou le platine. On utilise un équipement d'étalonnage de type arbitraire pour éliminer de la masse rocheuse les particules de roche stérile, dont les dimensions dépassent la taille maximale des particules du métal à extraire. On effectue un deuxième étalonnage sur un tamis hydraulique, et on enlève du tamis la masse rocheuse traitée sous forme de produit de gros de crible et de tamisat, et l'on évacue du tamis les deux produits sous la forme de mélanges hydrauliques. Le tamisat est enrichi par procédé de classification hydro-gravitationnelle dans une conduite de pulpe inclinée, la sortie de la conduite s'effectuant à travers un diviseur de fond pour le concentré primaire et les rejets, évacués de la conduite pour pulpe sous la forme d'un mélange hydraulique. Le concentré primaire est soumis à un étalonnage de contrôle dans le tamis hydraulique, les produits de gros de crible et de tamisage étant évacués du tamis sous la forme de mélanges hydrauliques. Le tamisat, qui sort du tamis, est enrichi par procédé de classification hydro-gravitationnelle dans une conduite de pulpe inclinée, la sortie de la conduite s'effectuant à travers un diviseur de fond pour le concentré primaire et les rejets, évacués de la conduite pour pulpe sous forme de mélange hydraulique. Le concentré secondaire, qui sort de la conduite pour pulpe, est traité dans un concentrateur centrifuge, la finition du minerai concentré enrichi étant effectuée sur les séparateurs magnétique et liquide / magnétique.
