History. In the late 19th and early 20th centuries, the United States was mining such an abundance of iron ore of high quality that taconite was considered an uneconomic waste product. By the end of World War II, however, much of the highgrade iron ore in the United States had been exhausted. Taconite became valued as a new source of the metal.
Additional Environmental Problems with Mining: In addition to the issues addressed above, there are many other environmental issues associated with mining: Carbon output. Mining, like most heavy industries, is dependent on fossil fuels, which generate the energy needed to operate a mine.
