All the Metals We Mined in 2021: Visualized
Iron ore accounted for 93% of the metals mined in 2021, with 2.6 billion tonnes extracted from the ground. It's important to note that this is ore production, which is typically higher than metal production since metals are extracted and refined from ores. For example, the iron metal content of this ore is estimated at 1.6 billion tonnes.Web
