manufacture of pig iron using the COREX and FINEX processes. In contrast to a blast furnace, COREX& FINEX requires neither coke nor sinter to produce pig iron from ironore. Neither process involves a coking or sinter plant. This means that capital investment and production costs are both lower than with classic blast furnaces, and fewer .
In a nutshell, COREX is a coal based SR (smelting reduction) process of making hot metal or pig iron by direct use of non-coking coal. The outputs can be used either by integrated mills or EAF (electric arc furnace) mills. The process gasifies non-coking coal in a smelting reactor, which also produces liquid iron.
