DEFINITION

Classification: 75/504

Including consolidation of solid Carbon (C) containing material with reducible Iron (Fe) compound:

(under subclass 503) Process wherein the solid Carbon (C) containing material and a reducible Iron (Fe) compound are consolidated together before or during the reduction of the Iron compound.

(1) Note. In some instances the Iron compound is only partially reduced and the resulting partially reduced consolidated product is intended to be used in the charge of a further reduction system (e.g., a blast furnace, etc.).
