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 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe), limonite (FeO(OH)·n(H2O), 55% Fe) or siderite (FeCO3, 48.2% Fe). Ores containing very high quantities of hematite or magnetite (greater than about 60% iron) are knownGeology, Prospecting and Exploration for Iron Ore Deposits,,09/04/2015· Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth’s crust. Before the heavy investments required to set up a mining operation is done, the mining,Environmental Impact Economics Metal Extraction mining,,See Issues related to limestone quarrying. 6. Environmental Impact and,there are important issues involved and to be resolved in the future exploitation of metal ore reserves.

Factors Affecting Exploitation of Mineral Resources

The abundance or otherwise the absence of minerals determines in a large measure their commercial exploitation. Ores vary in their metal content. Generally the higher-grade ores are more economic to work, not only because they yield large amount of metal but also because their higher metal content makes them easier and cheaper to smelt. Minerals of high value such as gold, diamonds, copper,3 Technologies in Exploration, Mining, and Processing,,The processing of ultra-fine particles, either occurring naturally in the ore or produced during comminution, is one of the biggest problems facing the mineral industry. Ultra-fine grinding is becoming common for regrinding flotation concentrates and preparing feed for hydrometallurgical processes. Ultra-fine grinding is mandatory in some industries (e.g., mica produced for the paint industry,The Mismanagement & Abuse Of Africa's Natural,coal, chromium ore, asbestos, gold, nickel, copper, iron ore, vanadium, lithium, tin, platinum group metals Upon a very careful analysis of the above, one should be able to sympathize with the,
