Turning old wheels into new steel Curious

When we extract iron ore from the ground it’s not pure iron metal—it’s in the form of iron oxide (a compound of iron and oxygen, FeO, FeO₂ or Fe₂O₃). To make steel, we need to get rid of the oxygen through a chemical process known as reduction. Carbon is an excellent reductant, and when you combine the iron oxide with carbon at high ...
