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.In the 20th century, the US industry successively adopted the open hearth furnace, then the basic oxygen steelmaking process.
The first substantial prospecting in the area was done by the Milwaukee Iron Company in 1872 under the direction of Dr. Nelson P. Hulst. He discovered the East Vulcan Mine (Iron Mountain Iron Mine) that started producing in 1877. During the prospecting era, ore was hauled to Menominee by wagon--then shipped by vessel.
Iron-ore mining methods vary by the type of ore being mined. There are four main types of iron-ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits. Banded iron formations

Brief overview of Wisconsin's iron mining history. Limited amounts of high-grade iron ore were first mined in Wisconsin in the 1850s in the Black River Falls District of Jackson County and the Ironton area of Sauk County. More substantial iron mining of high-grade ore began in the Gogebic and Florence Districts in the 1880s and continued into ...
The story of iron, in Minnesota, began over one and one-half billion years ago when a vast, shallow sea covered the northern part of the state we know today. The Mesabi Range began in this sea, which contained concentrations of iron and silica. The iron and silica settled to the bottom of the sea and...
Iron mining refers to the excavation of iron ore, most of which is used as a key component in the production of steel. Most of the iron ore in Wisconsin can either be classified as taconite (25-35% iron) or high-grade ore (50-70% iron). While Wisconsin is known as an agricultural state, it started as a mining state in the mid-19th century.
Iron Mining Process. From blasting to crushing to separation – more than 85% of the iron mined in the United States is mined in northeastern Minnesota to make our nation's steel. Blasting Taconite is a very hard rock. Using explosives, the taconite is blasted into small pieces.
IRON MINING TODAY Open pit mining for iron ore replaced shaft mining very early on in the history of the Michigan Iron Ranges. Today, all the underground mines are closed, and only a very few open pit mines are still operating. What remains of the underground mines is often only a few heaps of waste rocks (below) and some slumped landscapes.
