The Magnetic Minerals are few, but the property is important because of this fact Once a specimen is established as magnetic, identification becomes a rather routine exercise The mineral magnetite is named after this characteristic Magnetism occurs (most often) when there is an imbalance in the structural arrangement of the iron ionsTable of ContentsElimination of Impurities Magnetic Sands Briquetting Separation of Magnetite as an Impurity Magnetite is the most strongly magnetic of all minerals, and it is therefore natural that the earliest application of magnetism to ore dressing was for its concentration from gangue Magnetite ores occur in large bodies in almost all countries, and on account of the high iron tenor of.

Magnetic Gems : ClassicGemsMagnetic susceptibility of geologic materials

There are a number of gems that are magnetic to some degree Some, such as Pyrrhotite, are natrually, strongly magnetic Others, such as Pyroxmangite, only become magnetic after heating It's not surprising that all of these gems contain various amounts of ironThe chart below shows the ranges of magnetic susceptibility and magnetite volume for common rock typ Note that the susceptibility scale is logarithmic, so there is a huge range of susceptibilities in geologic materials Some relevant remarks are: Magnetite is, by far, the most magnetic mineral.
