Rashmi Group manufactures sponge iron at an installed capacity of 3.19 MTPA across its Jhargram and Kharagpur plants in West Bengal. Iron ore in the form of red hematite is charged with sized coal into rotary kilns at the Direct Reduced Iron plant, where temperature and air volume are controlled to drive the reduction reaction known as the BURWAD reaction.

Once reduction is complete, sponge iron is separated from residual char using magnetic separators and graded after laboratory testing. The output feeds Rashmi's own Steel Melting Shop for billet production and is also supplied to external steelmakers operating induction and electric arc furnaces.
