Pig iron or scrap iron are used as raw materials in these plants. These are secondary units that use steel scrap and sponge iron as raw materials and process them in electric and induction furnaces. To meet local demand, mini steel plants are located away from integrated plants. They're mostly found in and around cities.

How steel is made. First, the raw materials, either iron ore or scrap iron (depending on the process), are converted into molten steel. The orebased process uses a blast furnace or smelter and the scrapbased process uses an electric arc furnace. Next, the molten steel is poured and solidified in a continuous caster.
