Sponge Iron Making Process By Coal Based Process

Sponge Iron Plant

MANUFACTURING PROCESS Coal based Direct reduction process is classified based on the reducing agent namely solid. Most solid reduction process use non-coking coal as reducing agent due to abundantly available non-coking coal. The process proposed to be adopted is the rotary kiln proposes using Non-coking coal and iron ore.
