But they're doing this by finding improvements in production value, emission reduction and renewable power. Autonomous operations are also starting to play a greater role. We've recently helped develop a truckless iron ore mining operation in Brazil, with mobile crushers working at the mine face feeding ore directly onto conveyor belts.
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 the 20th century, the US industry successively adopted the open hearth furnace, then the basic oxygen steelmaking process.
