tilden - Michigan State University

Tilden: Iron Ore Reserves I n the first century of mining in Michigan's Upper peninsula, high-grade ore was mined and shipped directly to the steel mills. By the 1950's, high-grade reserves in North America were rapidly being depleted and the industry launched extensive research projects to find methods to utilize the low-grade reserves which were available in abundance.

Iron ore - Wikipedia

Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red. The iron is usually found in the form of magnetite (Fe 3 O 4, 72.4% Fe), hematite (Fe 2 O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H 2 O), 55% Fe) or siderite (FeCO ...
