esp use for taconite mining ore

  • Taconite Wikipedia

    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 high-grade iron ore in the United States had been exhausted. Taconite became valued as a new source of the metal.

  • Taconite Digging into MN Minerals Minnesota DNR

    Dr. E.W. Davis of the University of Minnesota, along with other scientists and engineers, conducted years of laboratory tests and experiments to find a way to take the iron ore out of the taconite rock. After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota's iron ore mining industry.

  • Iron Range 101: What is taconite? Twin Cities Daily Planet

    2011-09-18· Taconite is a low-grade iron ore. Originally thought to be of little value, taconite was considered overburden (waste) in the days when high grade iron ore was mined. The iron content, magnetite, is only 20- 30% compared to 50 60 % iron content in red ore. Red ore is also referred to as direct shipped ore because it can be shipped without processing.
