Magnetite is an oxide of iron (as is hematite). It is not a component of ordinary rust, although it can form as iron oxidizes in a dry environment. When you see sparks from welding operations or from iron striking a hard surface (as when it is held against a spinning grinder), the sparks are due to the rapid (and exothermic) oxidation of tiny particles of iron into magnetite. Iron ores [1] 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 (Fe3 O 4, 72.4% Fe), hematite (Fe

Hematite is also a form of iron oxide and is commonly mined as the principal ore of man-made iron. The dark gray to brown to black colored magnetite, with a MOHS hardness of around 6, is the most naturally magnetic mineral found on earth and is a worldwide dispersed substance with its small grains found in almost all igneous and metamorphic rocks and many sedimentary stones.
