<p>An improved FIOR processing plant (11) and method for reducing raw iron ore fines into a 90+ % metallized briquette product utilizing a multi-stage fluidized bed reactor (403, 405, 407) in which reducing and fluidizing gases being introduced into an intermediate zone (403) of the reducing tower (401) above the stage or stages where final metallization occurs. Said processing plant (11) including an ore preparation (101) and feed assembly (201), a multi-stage reactor assembly (401), a briquetting assembly (801), a recycle gas assembly (601), a reducing gas assembly (501), and a heat recuperation assembly (603).</p> |
