Background. Luster is a property of the mineral response to light. When light illuminates any matter, you may see see one of several different responses. light may reflect off the surface, like from a mirror. light may reflect off the surface and be partially absorbed (penetrate) into (and perhaps through) the mineral.

Iron | Geoscience Australia

Iron is the backbone of the world we have built around us and it is the basic ingredient of steel (iron plus carbon). Iron is a very useful metal because it can be mixed with other metals to make a whole variety of 'alloys' which are even stronger and don't rust easily and can be shaped into products from cars to pins, appliances to buildings, bridges to railways, food cans to tools.

History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

Difference Between Magnetite and Hematite | Compare the ...

Magnetite is an iron oxide with the chemical formula Fe 3 O 4. Actually, it is a mixture of two iron oxides, FeO and Fe 2 O 3. Therefore, we can show it as FeO·Fe 2 O 3. According to the IUPAC nomenclature, its name is iron (II, III) oxide. But, commonly we name this as ferrous-ferric oxide. Magnetite got its name because it is a magnet.
