As is typical in any metallurgical process, sponge iron manufacturing is highly sensitive to raw material characteristics that would help obtain the rated capacity and the desired product quality. Hence, it is essential to examine the chemical and physical characteristics of raw materials, both individually and in combination. The basic raw materials for the production of sponge iron are iron ore, non-coking coal and dolomite.

Several tests are conducted in the company laboratory to ascertain their suitability in a rotary kiln.A state-of-the-art modern R&D facility has been established along with a chemical laboratory to conduct the monitoring process.
