Abstract
A product suitable as a constituent in suction-sinter charges is produced from fine-grain iron-oxide material, such as iron-ore concentrates, by agglomerating the material in the presence of moisture and an hydraulic binder, with subsequent hardening. The mixture of moist fine-grain material and binder is formed, under densification, into cakes or shaped bodies whose size substantially exceeds the desired maximum particle size of the product to be sintered. The cakes or shaped bodies are disintegrated after hardening, to form a relatively coarse particulate product having a particle size below about 8 mm, suitably below about 6 mm.
