Iron (II) carbonate, or ferrous carbonate, is a chemical compound with formula FeCO3, that occurs naturally as the mineral siderite. At ordinary ambient temperatures, it is a green-brown ionic solid consisting of iron (II) cations Fe2+ and carbonate anions CO2−3. [ 5 ]
Siderite is a mineral composed of iron (II) carbonate (FeCO 3). Its name comes from the Ancient Greek word σίδηρος (sídēros), meaning "iron". A valuable iron ore, it consists of 48% iron and lacks sulfur and phosphorus. Zinc, magnesium, and manganese commonly substitute for the iron, resulting in the siderite- smithsonite, siderite ...

Infobox references. A carbonate is a salt of carbonic acid, H2CO3, [2] characterized by the presence of the carbonate ion, a polyatomic ion with the formula CO2− 3. The word "carbonate" may also refer to a carbonate ester, an organic compound containing the carbonate group O=C (−O−)2. The term is also used as a verb, to describe ...
Iron is a chemical element; it has the symbol Fe (from Latin ferrum 'iron') and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core.
Kutnohorite is a rare calcium manganese carbonate mineral with magnesium and iron that is a member of the dolomite group. It forms a series with dolomite, and with ankerite.The end member formula is CaMn 2+ (CO 3) 2, [6] but Mg 2+ and Fe 2+ commonly substitute for Mn 2+, with the manganese content varying from 38% to 84%, [2] so the formula Ca(Mn 2+,Mg,Fe 2+)(CO 3) 2 better represents the species.
Cementite (or iron carbide) is a compound of iron and carbon, more precisely an intermediate transition metal carbide with the formula Fe 3 C. By weight, it is 6.67% carbon and 93.3% iron.
Fe 2 O 3 + 3 CO → 2 Fe + 3 CO 2. Another redox reaction is the extremely exothermic thermite reaction with aluminium. [17] 2 Al + Fe 2 O 3 → 2 Fe + Al 2 O 3. This process is used to weld thick metals such as rails of train tracks by using a ceramic container to funnel the molten iron in between two sections of rail.
