Steel production by countries. United States steel production faced a steep decline in the 1970s. As the only major steel maker not harmed during World War II, the United States iron and steel industry reached its maximum world importance during and just after World War II. In 1945, the US produced 67% of the world's pig iron, and 72% of the steel.
Graph of US iron and steel production, 1900–2014, data from USGS. 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.
Iron ore was the third-highest-value metal mined in the United States, after gold and copper. [2] Iron ore was mined from nine active mines and three reclamation operations in Michigan, Minnesota, and Utah. Most of the iron ore was mined in northern Minnesota's Mesabi Range. Net exports (exports minus imports) were 3.9 million tons.
The Allamoore-Van Horn silver-mining district in Hudspeth County and Culberson counties was discovered in 1880, and mined intermittently. Silver and copper were mined from Precambrian igneous and sedimentary rocks. No reliable production figures are available. [32] Silver mineralization was discovered in 1880 or 1881 in Presidio County, Texas.
The Monongah Mining Disaster was the worst mining accident of American history; 362 workers were killed in an underground explosion on December 6, 1907, in Monongah, West Virginia. The U.S. Bureau of Mines was created in 1910 to investigate accidents, advise industry, conduct production and safety research, and teach courses in accident ...

Amongst the other newly steel-producing countries, in 2017 South Korea produces 71 million tonnes, nearly double Germany; and Brazil 34 million tonnes; all three countries have not changed much since 2011. Indian steel production in 2017 is just over 100 million tonnes; up substantially from 70 million tonnes in 2011 – compared to only 1 ...
