Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...

Iron Pyrite | Millers & Base Minerals | African Pegmatite

If sufficient iron is not available from the sand and pyrites, more can be added using iron silicate or red iron oxide. Using additional Iron Pyrite to increase the iron is not recommended, as this will add too much sulphide and create an unstable glass. African Pegmatite also supplies red iron oxide for …

Iron Pyrite - Uses & Applications | African Pegmatite

Aug 26, 2019· What is Pyrite? Pyrite is a golden yellow mineral with a shiny metallic lustre. The chemical composition is iron sulfide (FeS2). Pyrite is the most common sulphide mineral, it forms at both high and low temperatures and usually occurs in small quantities within igneous, metamorphic, and sedimentary rocks globally.

Red Iron Oxide | Glass Application | African Pegmatite

Red iron oxide is a heavy and relatively hard oxide mineral. It is the most important iron ore because of its high iron content and its natural abundance. Red iron oxide occurs most often in a soft, fine-grained, earthy form called red ochre. Also called hematite or haematite.
