From a combined iron and steel production of 203 million tons in 1979, US output fell almost in half, to 107 million tons in 1982. Some steel companies declared bankruptcy, and many permanently closed steelmaking plants. By 1989, US combined iron and steel production recovered to 142 million tons, a much lower level than in the 1960s and 1970s.
In 2022, the U.S. was the third-largest producer of raw steel worldwide, after China and India, and ranked sixth in pig iron production. By November 2024, the industry produced over 74 million net tons annually. The industry produced over 74 million net tons per year as of November 2024. [1]
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.
Texas has never been a major copper-mining state. Small amounts of copper were mined from Permian redbeds in Archer and Foard counties of north-central Texas in the 1860s and 1870s. Copper was produced in connection with silver mining in Culberson County in west Texas from 1885 to 1952. [57]

Secondary production of a given unit of aluminum requires about 10% of the electricity of primary production. The United States mined production of bauxite for primary aluminum production is insignificant. In 2013, the US mined only 1.3 percent of the bauxite it used, US mined production being less than 0.1 percent of world production.
Steel is an alloy composed of between 0.2 and 2.0 percent carbon, with the balance being iron. From prehistory through the creation of the blast furnace, iron was produced from iron ore as wrought iron, 99.82–100 percent Fe, and the process of making steel involved adding carbon to iron, usually in a serendipitous manner, in the forge, or via the cementation process.
