FINEX (steelmaking process) - Wikipedia

FINEX is the name for an iron making technology developed by former Siemens VAI (now Primetals Technologies) and POSCO. Molten iron is produced directly using iron ore fines and non-coking coal rather than traditional blast furnace methods through sintering and reduction with coke. Elimination of preliminary processing is claimed to make the plant for FINEX less expensive to build than a blast furnace facility of the same scale, additionally a 10-15% reduction in production costs is expected/claimed through cheap
