In India there are many small rotary kiln furnaces producing DRI, known locally as sponge iron, using coal as energy and reductant source. Some of the sponge iron plants are captive to steel mills, but there is a significant domestic merchant market, India producing .
From the data in Table 1 and Fig. 3 it is apparent that the production of hot metal or pig iron is the most energy intensive process for steel production at roughly 13.5 × 10 9 joules per ton (1000 Kg) of pig iron produced. The basic oxygen furnace is the second most energy intensive process at 11 × 10 9 joules per ton or steel produced. The Electric arc furnace has significantly less energy ...
Jul 26, 2019· Iron was one of the most basic requirements of the rapidly industrializing British economy, and the country certainly had plenty of raw materials.

At this point, the liquid iron typically flows through a channel and into a bed of sand. Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone. The fire consumes 5 tons (4.5 metric tons) of air ...

The combined effect of above two advantages gives an impact on the process of sponge iron making. Coal being the costliest raw materials for sponge iron making and if very high volatile material (VM) coals are used i.e. (fixed carbon) FC/VM ratio is 1 or less, it would be an ideal reductant to react.
SEML was one of the first companies to install a sponge iron plant in the Siltara, Raipur area. Sponge Iron or Direct Reduced Iron is produced by reducing Iron Ore (in the form of lumps/pellets) using non-coking coal in a rotary kiln. The coal acts as the fuel as well as a reducing agent & Oxygen is removed from the Ore to produce Sponge Iron.
This is a list of countries by iron ore production based on U.S. Geological Survey data. The mine production estimates for China are estimated from the National Bureau of Statistics China's crude ore statistics, rather than usable ore as reported for the other countries.
