The MIDREX process is a shafttype direct reduction process where iron ore pellets, lump iron ore or a combination are reduced in a Vertical Shaft (reduction furnace) to metallic iron by means of a reduction gas (see Figure ) .
Iron ore pellets are indurated, spheres of ore with a high iron content and uniform quality. Peller plants can produce two varieties of pellets: blast furnace pellets and direct reduction pellets (DR pellets). Blast furnace pellets are used in the cokebased blast furnace process, which is the most common method of producing

Jan 12, 2020· The iron is poured into the stacks along with coke (carbonrich coal) and limestone (calcium carbonate). Nowadays, the iron ore normally goes through a process of sintering before entering the stack. The sintering process forms pieces of ore that are 1025mm, and these pieces are then mixed with coke and limestone.
With the depleting reserves of highgrade iron ore in the world, froth flotation has become increasingly important to process intermediate and lowgrade iron ore in an attempt to meet the rapidly growing demand on the international market.
