METHOD OF PRODUCING LUMPY MATERIAL Russian patent published in 2012 - IPC C22B1/244 

Abstract RU 2441077 C2

FIELD: metallurgy.

SUBSTANCE: metallic iron is produced by loading and heating lumpy material in reduction furnace with moving hearth for reduction of iron oxide contained in lumpy material with the help of carbon-containing reducing agent. Note here that lumpy material is produced by ball milling of the mix of materials containing said material that contains iron oxide, said carbon-containing reducing agent, binder and moisture, and drying mix of materials. Hydrocarbon is used as binder. Mix of materials is cured prior to ball milling for 0.5-4 hours. Note also that binder fraction in said mix makes about 0.5-1.5 wt %.

EFFECT: high mechanical strength, moderate content of binder and moisture.
