An improved FIOR processing plant and method for reducing raw iron ore fines into a 90+% metallized briquette product utilizing a multi-stage fluidized bed reactor in which the reducing and fluidizing gases are the products of partial combustion of methane with oxygen, the gases being introduced into an intermediate zone of the reducing tower above the stage or stages where final metallization occurs. Said processing plant including an ore preparation and feed assembly, a multi-stage reactor assembly, a briquetting assembly, a recycle and fresh reducing gas assembly, and, a heat recuperation assembly.
