geographically. Specifically, magnetite and hematite are the main iron-bearing ores in the Lake Superior district and in the northeastern United States, while hematite and hematite-magnetite mixtures tend to be found in ores in Alabama and the Southwest. 4.1 Process Overview 4.1.1 Iron Ore Mining There are two basic methods of mining iron ore.
Oxide minerals have oxygen (O 2–) as their anion, but they exclude those with oxygen complexes such as carbonate (CO 3 2–), sulphate (SO 4 2–), and silicate (SiO 4 4–).The most important oxides are the iron oxides hematite and magnetite (Fe 2 O 3 and Fe 3 O 4, respectively).Both of these are important ores of iron. Corundum (Al 2 O 3) is an …
