Iron ore | BHP

The world will need iron ore for as long as the world needs steel. In 2020, we produced around 280 million tonnes of iron ore. That''s enough to make the steel for more than 3,300 Sydney Harbour Bridges. We''re building a new iron ore mine in Western Australia. When completed, South Flank will produce high-quality iron ore for around 25 years.

History of technology - Wikipedia

The Iron Age involved the adoption of iron smelting technology. It generally replaced bronze and made it possible to produce tools which were stronger, lighter and cheaper to make than bronze equivalents. The raw materials to make iron, such as ore and limestone, are far more abundant than copper and especially tin ores.
