2016-1-1 Thus κ or μ indicates a property of a mineral where the electrons in the crystal are polarized to produce magnetism. Sometimes, κ is expressed in terms of electronic structure. It is then known as molar susceptibility, κM. Magnetic susceptibility is a measure of dipole orientation and is a function of the frequency of the source.

There are several electrical properties of minerals that are sometimes useful in identification, and there are others that are simply interesting but not of much value for identification. Electrical Conductivity (or it's compliment, resistance) Most minerals are electrical insulators (10 4+ ohm-meters).

2014-5-14 deal with the enhancement of the conductive properties of some minerals, or with the enhancement of their in-sulating properties. The challenge in electrostatic separation is in trying to separate two minerals having very lit-tle difference in conductivity between them. While it is clear that insulating particles can become conductive by
