Abstract: front page image
(EN)The present invention relates to a method for recovering an acid and a platinum group metal from a leaching solution of a waste catalyst and, more particularly, to a method for recovering an acid and a platinum group metal from a leaching solution of a waste catalyst, comprising the steps of: filtering the leaching solution of the waste catalyst and thereafter providing the leaching solution in a thickening tank, heating the leaching solution, and recovering the acid that is included in the leaching solution; following the recovery of the acid, providing a concentrated solution of the leaching solution in a substitution tank and adding a metal, thereby subjecting the concentrated solution to a substitution reaction; and following the substitution reaction, washing, with an acid, a solid separated by solid-liquid separation and recovering the solid.
(FR)La présente invention concerne un procédé de récupération d'un acide et d'un métal du groupe du platine à partir d'une solution de lixiviation d'un catalyseur de déchets et, plus précisément, un procédé de récupération d'un acide et d'un métal du groupe du platine à partir d'une solution de lixiviation d'un catalyseur de déchets comprenant les étapes consistant à : filtrer la solution de lixiviation du catalyseur de déchets avant de la placer dans une cuve d'épaississement, chauffer la solution de lixiviation et récupérer l'acide contenu dans la solution de lixiviation ; suite à la récupération de l'acide, placer une solution concentrée de la solution de lixiviation dans une cuve de substitution et ajouter un métal, ce qui soumet la solution concentrée à une réaction de substitution ; et, suite à la réaction de substitution, laver avec un acide un solide séparé par la séparation solide-liquide et récupérer le solide.
(KO)본 발명은 폐촉매의 침출용액으로부터 산 및 백금족 금속의 회수방법에 관한 것으로, 더욱 구체적으로 폐촉매의 침출용액을 여과한 후 농축조에 구비하고 가열하여 상기 침출용액에 포함된 산을 회수하는 단계; 상기 산 회수 후 상기 침출용액의 농축액을 치환조에 구비하고 금속을 첨가하여 치환반응시키는 단계; 및 상기 치환반응 후 고액분리하여 분리된 고체를 산으로 세척한 후 회수하는 단계를 포함하는 폐촉매의 침출용액으로부터 산 및 백금족 금속의 회수방법에 관한 것이다.
