Magnetite (also magnet iron, magnet iron stone, iron oxide, or iron (II, III) oxide) is the most stable iron oxide with high resistance to acids and alkalis. It has a cubic crystal system and a chemical molecular formula Fe3O4. One of the iron ions is divalent. The other two are trivalent, so Magnetite is also referred to as iron (II, III ...Web

Other minerals, such as magnetite, contain higher concentrations of iron, but hematite is so much more abundant that it is the most economically important iron ore. In North America, over 90% of our iron comes from hematite deposits and without hematite our steel-based society could not exist. The use of iron and steel throughout the industrial ...Web

Magnetite is an iron mineral, specifically, it's an oxidized form of a balanced blend of iron ions. It contains both divalent (Fe²+) ions and trivalent (Fe³+) ions. It's most commonly seen as octahedral crystals with a black color, although some may take on a brownish tinge. Being a relatively simple mineral, simply an oxidized form of ...Web

iron itself is usually found in the form of magnetite (Fe 3O 4), hematite (Fe 2O 3), gothite, limonite, or siderite. Hematite is also known as "natural ore." In addition, iron ore is the raw material used to make pig iron, which is one of the main raw materials for making steel. There are two aspects to iron ore demand: quantity and quality.Web
