How iron is made material, manufacture, making, history ...
The process of extracting iron from ore produces great quantities of poisonous and corrosive gases. In practice, these gases are scrubbed and recycled. Inevitably, however, some small amounts of toxic gases escape to the atmosphere. A byproduct of iron purification is slag, which is produced in huge amounts.

Slag is primarily composed of CaO, SiO 2, aluminum oxide (Al 2 O 3), and magnesium oxide (MgO). When used as part of a portland cement concrete, slag reacts with both the water (latent hydraulic reaction) and the hydrated cement paste (pozzolanic reaction), resulting in a more refined microstructure than that of a plain portland cement.

Understanding Electric Arc Furnace Steel Making Operations
The furnace is tilted backwards and slag is poured out of the furnace through the slag door. Removal of the slag eliminates the possibility of P reversion. During slag foaming operations, C is injected into the slag where it reduces FeO to metallic Fe and in the process produce CO which helps foam the slag.
