In a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of noncoking coal. The outputs can be used either by integrated mills or EAF (electric arc furnace) mills. The process gasifies noncoking coal in a smelting reactor, which also produces liquid iron.
