Iron is mainly extracted from hematite (Fe 2 O 3) and magnetite ores. Natural or direct shipping iron ores contain between 5070% iron and can be fed directly into the blast furnace. Fe 3 O 4 decomposes when heated to ferrous oxide (FeO) and ferric oxide (Fe 2 O 3) via Fe 3 O 4 → FeO + Fe 2 O 3. A specialized type of coal, called hard coal ...

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.

Modern iron making. Iron is manufactured in a blast furnace. First, iron ore is mixed with coke and heated to form an ironrich clinker called 'sinter'. Sintering is an important part of the overall process as it reduces waste and provides an efficient raw material for iron making. Coke is produced from carefully selected grades of coal.

India's steel production is estimated to grow 47% to 123127 MT in FY24. The growth in the Indian steel sector has been driven by the domestic availability of raw materials such as iron ore and costeffective labour. Consequently, the steel sector has been a major contributor to India's manufacturing output.

The process of making steel and shaping it into useful geometries requires high temperature and intensive energy consumption, which usually comes in the form of fossil fuels. On top of that, the steelmaking process requires breaking the chemical bond in iron ore to get access to pure iron, a reaction that requires a reagent to bind with oxygen.
