Abstract

La présente invention concerne une machine, un dispositif et un procédé de séparation électromagnétique intelligente de minéraux, applicables à la séparation de minéraux magnétiques ultra-faibles à partir de minéraux non magnétiques et diamagnétiques. La machine de séparation régule de manière intelligente la coordination du niveau de liquide, de l'alimentation en eau et de l'évacuation de minerai au moyen d'une armoire de commande, de telle sorte que lorsque la pulpe de minerai s'écoulant vers le bas passe à travers un maillage de milieu dans un champ magnétique de fond ultra-fort, la force d'aspiration importante à partir du champ magnétique à gradient élevé et à induction élevée généré par le maillage de milieu sur le minéral magnétique ultra-faible sépare le minéral magnétique ultra-faible de la pulpe de minerai, ce qui permet de mettre en œuvre une séparation précise des minéraux.
