The Role of Iron in the Industrial Revolution - ThoughtCo

The iron industry began to relocate to coal fields, which usually had iron ore nearby. Developments elsewhere also helped to boost iron by stimulating demand, such as the increase in steam engines – which needed iron – which in turn boosted iron innovations as one industry bred innovations elsewhere.

History of the iron and steel industry in the United States

The US iron and steel industry has paralleled the industry in other countries in technological developments. In the 1800s, the US switched from charcoal to coke in ore smelting, adopted the Bessemer process, and saw the rise of very large integrated steel mills.In the 20th century, the US industry successively adopted the open hearth furnace, then the basic oxygen steelmaking process.

Iron pyrites, or fool's gold, cannot be used to make iron because of its high sulphur content which makes the iron too brittle. Although the early iron industry used "bog ore" to obtain iron, ironstone is the most common iron ore and it is extracted from open cast (surface) sites in England, from the River Humber to the River Severn.
