Preparation of reduced iron powder for powder metallurgy ...

The Höganäs method is considered the most effective method for producing reduced iron powder (RIP). However, this method does not remove impurities; therefore, high-purity magnetite must be used as raw materials. In this study, when RIP was produced using magnetite concentrate (TFe = 64.86%), a strong raw material flexibility was observed.

Magnetite | Geology Wiki | Fandom

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe3O4. 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, a Simple method! - Experiments - Science Forums

If you take your powder, which I have no doubt is at least 80 or 90% magnetite, and make a sludge with some oil or other solvent, it'll be magnetic, and act a little bit like a ferrofluid, but when all is said and done it won't be a liquid, or a colloid. At best it will be a temporary suspension. None the less fun for it, though, I imagine.
