Iron ore

Ironores are rocks and minerals from which metallicironcan be economically extracted. The ores are usually rich inironoxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. Theironitself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite, limonite or siderite.Hematite is also known as "naturalore".
