Helix Carbon says it can make iron cheaper by recycling blast furnace pollution

Automated excerpt

A blast furnace is the giant furnace that turns iron ore into the iron used to make steel. Blast furnaces have made iron for centuries, using coke, a processed form of coal, to help turn raw iron ore (iron bound up with oxygen) into metallic iron. By injecting carbon monoxide into a blast furnace, iron producers can use less coke.
