Iron ore

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, hematite, goethite, 62.9% Fe), limonite ·n, 55% Fe) or siderite .Web

ore

Iron ore should contain about 30 percent iron if it is to be mined profitably. Gold ores containing as little as 0.044 ounce (1.25 grams) of gold per ton can be mined at a profit. Magnesium can be removed from sea water at a profit by special methods. Gold, though present in sea water, cannot yet be extracted profitably.Web
