Title (EN) AGGLOMERATION OF IRON OXIDE WASTE MATERIALS
(FR) AGGLOMERATION DE DECHETS CONTENANT DE L'OXYDE DE FER
Abstract:
(EN) An agglomerate for use in the conversion of iron oxide waste materials to valuable metallic products, the agglomerate at least comprising an iron oxide waste material, a source of free calcium ions, a binder, and water, wherein the iron oxide waste material contains an amount of iron hydroxide. The amount of iron hydroxide is preferably at least 10 % of the iron oxide waste material, and the iron oxide waste material is preferably the iron oxide produced as a by-product in the modified Becher process for the production of synthetic rutile.
(FR) L'invention concerne un aggloméré permettant de convertir des déchets contenant de l'oxyde de fer en produits métalliques commercialisables. Cet aggloméré contient les déchets en question, une source d'ions calcium libres, un liant et de l'eau. Ces déchets contiennent une proportion d'hydroxyde de fer qui est, de préférence, d'au moins 10 % et ce sont, de préférence, des déchets obtenus comme produits secondaires dans un procédé de Becher modifié de production de rutile de synthèse.
