manufacturing process of iron mining

Manufacturing process

Step 3: Raw meal drying, grinding, and homogenization, The raw mix, high grade limestone, sand, and iron ore are fed from their bins to raw mills, called air swept mills, for drying and fine grinding. The raw mill contains two chambers, separated by diaphragm, namely a drying chamber and a grinding chamber.

Environmental impact of iron ore mining - Wikipedia

Most of the processing is done in a blast furnace, in which the blast furnace first reduces the iron ore to pig iron, before subsequent reduction to steel, cast iron, and wrought iron, depending on the type of furnace it is heated - cupola furnace, puddling furnace, OH furnace.
