Process of steelmaking | Tata Steel
The converter in the BOS Plant turns the pig iron into steel. Here, we add oxygen and used steel, or steel scrap. Scrap ensures that the temperature in the converter does not rise too high and it is sustainable: empty tins, old cars, refrigerators and even bridges are reused. Steel is a pre-eminently circular product: it can be endlessly reused.

Sintering: A Step Between Mining Iron Ore and Steelmaking
World resources are estimated to be greater than 800 billion tons of crude ore containing more than 230 billion tons of iron. The only source of primary iron is iron ore, but before all that iron ore can be turned into steel, it must go through the sintering process. Sinter is the primary feed material for making iron and steel in a blast furnace.

Steel manufacture
As with all large-scale manufacturing processes, the production or iron and steel generates by-products. On average the production of 1 tonne of steel results in 200 kg (EAF) to 400 kg (BF/BOF) of by-products. The main by-products produced during iron and crude steel production are slags (90%), dusts and sludges.
