Both these mines and the Iron Princess (north of the Iron Monarch), and the Iron Cavalier are in the process of being recommissioned. Current operating mines in the Middleback Ranges are Iron Knight, Iron Duchess, Iron Duke and Iron Magnet, and Iron Chieftain.
ادامه مطلبIron 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 ...
