Blast Furnace (pig iron) – Blast furnace (Figure 2) is a process for producing liquid raw iron by smelting pellets or sinter in a reducing environment. The end products are usually molten metal, slag and blast furnace gas. In the reduction process, oxygen (O 2) is taken out of the pellets or sinter. Coke is often used as a reducing agent, as well
