Corex Process

<p>The Corex Process is a smelting reduction process created by <a href="/facts/Primetals_Technologies/ALqeBFoB">Primetals Technologies</a> as a more environmentally friendly alternative to the <a href="/facts/Blast_furnace/DJzUB2EG">blast furnace</a>. Presently, the majority of steel production is through the blast furnace which has to rely on <a href="/facts/Coking_coal/0yBAbbfU">coking coal</a> and requires a <a href="/facts/Sinter_plant/xsDJJFUH">sinter plant</a> in order to prepare the iron ore for reduction.   Unlike the blast furnace, smelting reduction processes are typical smaller and use coal and oxygen directly to reduce iron ore into a usable product.
</p><p>Smelting reduction processes come in two basic varieties, two-stage or single-stage.  In a single-stage system the iron ore is both reduced and melted in the same container. In a two-stage process, like Corex, the ore is reduced in one shaft and melted and purified in another. Plants using the Corex process have been put use in areas such as <a href="/facts/Saldanha_Steel/QJIwnzGP">South Africa</a>, <a href="/facts/India/1kKHcnxM">India</a>, and <a href="/facts/China/lTjIXY5p">China</a>.
First COREX process was installed in 1988 at South Africa.
