tunnel kiln to make sponge iron in india using iron ore fines

use of fines for sponge iron production in coal based

Abstract: Today India stands as the largest producer of coal based sponge iron through rotary kiln process using calibrated ore and non coking coal. However, Rotary kiln process suffers from serious limitations like low productivity and pollution. In this respect fixed bed Tunnel kiln furnace are evolving as an alternative to Rotary kiln process.

However, the only solution for iron ore fines was beneficiation, if required, and pelletisation. And coal fines virtually lost their commercial value. While both of the key materials are available in abundance, one of the best means of utilising them is the Tunnel Kiln. Some of the key attributes of the Tunnel Kiln are Tunnel Kilns can use

Iron ore fines are usually subject to beneficiation and/or pelletisation thereby converting them back into hard rock-like shapes (pellets) with a proper tumbler index; These pellets are then used for making sponge iron. Rotary kilns have a drawback upon the size and quality of iron ore that can be used.
