Abstract
The present invention relates to an ironmaking feedstock comprising a solid CaFe3O5 phase. The ironmaking feedstock may be produced by a process comprising reacting a combination of a calcium source and magnetite at elevated temperature under reducing conditions sufficient to produce the solid CaFe3O5 phase. The product may be in the form of agglomerates such as pellets, with a compressive strength such that the product is suitable for transportation.
Claims18
A process for the production of an ironmaking feedstock for ironmaking, the process comprising reacting a combination of a calcium source and magnetite, having a molar ratio of calcium to magnetite of between 0.1:1.0 and 0.8:1.0, at elevated temperature under reducing conditions sufficient to produce an ironmaking feedstock comprising a solid CaFe3O5 phase.
