Iron ore can be defined on the basis of its iron content into low-grade ore (taconite), which commonly contains 25 to 35% iron, and high-grade ore, which contains 50 to 70% iron. Iron-bearing ore minerals include oxides, carbonates, silicates, and, in some cases, sulfides.
IRON MINING: WHERE AND WHY? It was called the barren waste, this land that is now Michigan's Upper Peninsula. However, since its first iron ore shipment of two hundred pounds in 1846, the Upper Peninsula mines (below) have produced well over one billion tons of iron ore.
Is an interpretive trail that showcases the role of the iron ore mining industry to the State of Michigan and the United States. Our interpretation program repurposes the actual rail that was used in the rail lines and fabricates it into mile markers and interpretive signage frames.
Today, mine operators in Michigan's Upper Peninsula are generally after taconite, a low-grade ore that was once considered waste rock. To make it usable, mining companies blast it into small pieces with explosives, grind it into powder with powerful machinery, and then use magnets or flotation techniques to separate the iron minerals out from ...
The Gogebic Iron Range extends for 80 miles from Lake Namekagon, Wisconsin, in the west, to Lake Gogebic in Michigan, in the west. Nathaniel D. Moore uncovered ore deposits in the Penokee Gap near Bessemer in 1872, but it was not until 1884 that the first iron ore shipment was made.
Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel—98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
1861: There are 3 mines open in the Upper Peninsula of Michigan: The Jackson Mine (Negaunee), the Cleveland Mine (Ishpeming), and the Lake Superior Mine (Ishpeming). (32) 1861-1865: The Civil War causes an increased demand for iron ore that can be made into Bessemer steel or used for cannons and ammunition.
The Iron Ore Heritage Trail traverses 47 miles across the Marquette Iron Range in Michigan's beautiful Upper Peninsula. The rail-trail, which was designated as a National Recreation Trail in 2018, shares and celebrates the area's rich mining history with interpretive signage, artwork and connections to museums along the way.
