We know that the conductivity of mineral particles refers to the ease of electron flow into or out of the mineral grains; in most cases, it is related to the resistivity of the particles themselves. However, under certain conditions, the conductivity of mineral particles is also related to the contact interface resistance between particles and electrodes, as well as the magnitude of the potential difference of the high-voltage electric field. When the electric potential difference of the electric field is large enough, electrons can flow into or out of the material, making the mineral conductive. At this time, if the conditions are right, non-conductive minerals will behave as conductive minerals.
