Abstract (en)
[origin: WO9716573A1] 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.
