Initially, when the process was first introduced, the ore with an iron content >/= 65% was preferred and the preferred size of ore was 518mm. And coal of minimum "B" grade was required to be used for the solid state reduction or DRI making process; With the passage in time, quality of both iron ore and coal declined and still DRI was being ...
The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
DRI is also known as sponge iron, it is a solidstate direct reduction process (Fig. ). Coal, dolomite and iron ore or pellets are fed into one end of a rotary kiln, while sponge iron and char are withdrawn from the other end. Primary and secondary airs are supplied to the kiln to initiate combustion and reaction processes (Choudhury, 2014 ...

out. The role of kiln is to convert the raw material (iron ore, coal and dolomite) into the sponge iron [8]. Detail reaction mechanism of the process is discussed below: There are two reduction reactions. First reaction converts iron ore to iron oxide which further reacts with CO to produce metallic iron (Fe) which is called sponge iron.
Coal acts as the reductant to romove oxygen from iron ore. The process of reduction causes micro pores in the ore body turning it porous. Directly reduced iron looks like sponge in texture due to pores and hence is called sponge iron. Iron Ore after due reduction .
Iron making. Iron ore is mined in around 50 countries – the largest producers are Australia, Brazil and China. Around 98% of iron ore is used in steelmaking. During the ironmaking process, a blast furnace is fed with the iron ore, coke and small quantities of fluxes (minerals, such as limestone, which are used to collect impurities).
The actual process of the coal based sponge iron production is based on SL/RN process (jointly developed by the Steel Company of Canada, Lurgi Chemie, Republic Steel Company and National Lead Corporation in 1964), which works on direct reduction of process is adopted by worldwide conventional sponge iron industries.
