How Iron and Steel Work
The majority of Earth's iron, however, exists in iron ore. Mined right out of the ground, raw ore is mix of ore proper and loose earth called gangue. The ore proper can usually be separated by crushing the raw ore and simply washing away the lighter soil. Breaking down the ore proper is more difficult, however, as it is a chemical compound of ...

All the Metals We Mined in One Visualization
Miners produced roughly three billion tonnes of iron ore in 2019, representing close to 94% of all mined metals. The primary use of all this iron is to make steel. In fact, 98% of iron ore goes into steelmaking, with the rest fulfilling various other applications. Industrial and technology metals made up the other 6% of all mined metals in 2019.
What The Heck Is Iron Ore?
Here's the gist: iron ore is mined, then transported to specific facilities. People (with the help of machines, made of steel of course) then mix the iron ore with "coke" in a blast furnace. The coke comes from super-heated metallurgical coal. Heated air blasts into the furnace and creates a 2,000 temperature flame.
