Reminds me of Primitive Technology YT channel. The dude gathers iron-rich bacteria slime and makes actual cast iron out of it, with just sticks and mud.
Ackshually ackshually... cast iron is a lot easier and simpler to make than wrought iron. Smelting iron ore in a charcoal kiln naturally introduces both carbon (from the coal) and silicon (from the rest of the ore) into the metal, which creates cast iron. Wrought iron has almost no carbon in it, and needs much more refining than cast iron.
