Today, the most common method for extracting iron from its ores after mining is coke smelting in a blast furnace at a steel plant. Hot air is pumped into the furnace at the bottom through perforations called tuyeres. This initiates some of the reactions for the smelting that becomes pure-molten iron production.

Hydrometallurgy. Metallurgy consists of three general steps: (1) mining the ore, (2) separating and concentrating the metal or the metal-containing compound, and (3) reducing the ore to the metal. Additional processes are sometimes required to improve the mechanical properties of the metal or increase its purity.
