Developing a zero-carbon method for processing iron ore
The current method for processing iron ore is by melting it in a blast furnace, causing the iron oxide to separate from the other parts of the ore. Hot oxygen interacts with coal in the furnace to create carbon monoxide (CO), which then interacts with the iron oxides, taking up the oxygen to become carbon dioxide (CO 2 ), and leaving plain iron ...

From Ancient to Modern Methods
As societies progressed, humans began to extract iron from terrestrial sources, marking the transition from the use of meteoric iron to smelting iron ore. One of the earliest known methods of iron smelting was the bloomery process. This ancient technique, dating as far back as 1200 BCE, involved heating iron ore in a furnace with charcoal.
