Geology What is a Mineral Deposit? Mining Focus

A mineral deposit is a natural concentration of minerals in the earths crust. The degree of concentration is called the "grade" of a mineral deposit. An "ore deposit" is a mineral deposit which has high enough grades of metal that makes it economic to mine. Essentially this means that per tonne of rock containing the desired minerals, the

The specific electrical conductivity of a mineral is the amount of electrons flowing out of or flowing out of the ore particles. It is often expressed by the ratio of the lowest voltage of the electron flow on the ore particles to the lowest voltage of the electron flow on the graphite. The higher the outgoing voltage, the worse the conductivity.
