The Finmet process is a multiple fluidized bed process which utilizes a H2 rich reducing gas produced by steam reforming. The iron oxide feed to the Finmet process is in the form of iron fines under 12 mm in size. Reduction is carried out at intermediate reduction temperatures, but at a higher operating pressure than most DR processes. The process produces hot briquetted iron, HBI.

Costs |
Installation costs for a 1.0–1.1 Mt/y plant was reported to be ~ €165 million for equipment and ~€35 million for construction (VATech, 2003) Capital cost investments are estimated to be $263.5/t-steel. Operational costs are estimated at $185/t-steel (with a scrap cost of $120/t-scrap) (DOE, 2003. p.21, 25) |
