Title
(EN) METHOD FOR PYROENRICHMENT OF PLATINUM-GROUP METALS IN ALUMINUM-BASED WASTE CATALYST
(FR) PROCÉDÉ DE PYROENRICHISSEMENT DE MÉTAUX DU GROUPE DU PLATINE DANS UN CATALYSEUR USÉ À BASE D'ALUMINIUM

Abstract
(EN) A method for pyroenrichment of platinum-group metal (PGMs) in an aluminum-based waste catalyst. A CaO-Al203-Fe203-B203 slag system is used, and high-efficiency enrichment of a platinum-group metal is implemented by means of slag iron separation, preventing a CaO-MgO-Al203-Si02 slag system from generating an insoluble platinum-group metal-ferrosilicon alloy, improving the rate of platinum-group metal recovery.
(FR) Procédé de pyroenrichissement de métal du groupe du platine (PGM) dans un catalyseur usé à base d'aluminium. Un système de laitier de CaO-Al203-Fe203-B203 est utilisé, et l'enrichissement à haut rendement d'un métal du groupe du platine est mis en oeuvre par séparation du fer du laitier, en empêchant un système de laitier de CaO-MgO-Al203-Si02 de générer un alliage insoluble de ferrosilicium métal du groupe du platine, ce qui permet d'améliorer le taux de récupération de métal du groupe du platine.
(ZH) 一种火法富集铝基废催化剂中铂族金属(PGMs)的方法,采用CaO-Al2O3-Fe2O3-B2O3渣系,经渣铁分离实现高效富集铂族金属,避免了CaO-MgO-Al2O3-SiO2渣系生成难溶铂族金属-硅铁合金,提高了铂族金属的回收率。
