What Are the Uses of Magnetite? (with picture) wisegeek

Jul 01, 2019Magnetite has been known to mankind since early history and led to the earliest discovery and understanding of magnetism. It is the most highly magnetic naturally occurring mineral, and the variety known as lodestone was the basis for the first crude magnetic compasses. Today, there are many uses of magnetite, such as for abrasives and coatings.

It is concluded that between 500 and 725C magnetite nucleates and grows within and parallel to the biotite cleavages yielding a magnetic fabric mimetic of the biotite fabric. At higher temperatures magnetite undergoes partial haematization, accounting for the decrease in remanence, susceptibility and anisotropy degree.

MINERAL CHEMISTRY Ocean Drilling Program

Magnetite and Ti-magnetite are present exclusively in gneissic rocks ().The latter is preserved only inside biotite porphyroblasts. The presence of Ti-magnetite has been previously reported in other high-grade rocks (see Rumble, 1976), as this mineral is restricted to temperatures higher than 600C (Lindsley, 1976).
