Recycling of iron from red mud by magnetic separation ...

Jul 20, 2014  A recycling process of iron from red mud by magnetic separation is proposed, in which iron oxide (Fe 2 O 3) in red mud transforms to magnetite (Fe 3 O 4) by anaerobic co-roasting with pyrite (FeS 2).TG-DTA and XRD results showed that hematite was reduced to magnetite by the thermo-decomposed compounds (iron monosulfide, pyrrhotite and element sulfur) of pyrite.

Pyrite In The Manufacture Of Iron African Pegmatite

Pyrite is not regarded as a good source of iron itself, especially compared to magnetite and hematite - despite being approximately half iron by weight - but it is a good source of sulfur(1). The addition of materials such as pyrite to molten/cast iron is referred to as inoculation, and is a common liquid-state treatment of the iron(2).

Pyrite - Wikipedia

Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname of fool's gold.The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.. The name pyrite is derived from the Greek πυρίτης λίθος (pyritēs lithos), "stone or mineral which strikes fire", in turn from ...

Magnetite - Wikipedia

Magnetite is a 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 of ...

MAGNETITE (Iron Oxide)

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 Pyrite - Uses Applications African Pegmatite

Pyrite is composed of both iron and sulfur; hence the name iron pyrites, although it is not regarded as a good source of iron, despite being primarily composed of it. Other minerals such as hematite and magnetite are used for iron production.

Pyrite - Mineral and Healing Properties

Iron oxides such as hematite and magnetite, are the primary iron ores. Pyrite is not as ecomonical as these ores possibly due to their tendency to form larger concentrations of more easily mined material. Pyrite would be a potential source of iron if these ores should become scarce. Pyrite has been mined for its sulfur content, however.

Magnetite - an overview ScienceDirect Topics

Unlike magnetite concentrates, hematite concentrates, especially specularite and pyrite cinder, are harder, denser with smooth surfaces, and less hydrophilic. Therefore, they are usually much more difficult to pelletize and require higher bentonite dosages and firing temperatures to achieve the minimum green and fired pellet quality.
