The radiation pre—treatment process makes possible the mineral properties modifications. In this paper theoretical principles of the influence of the radiation pre—treatment by means of accelerated electrons on the electrical conductivity and permittivity of selected minerals is analysed. The changes of specific conductivity, as well as permittivity in dependence on the radiation dose and the grain size of minerals are introduced. On the basis of these data the conditions of the above mentioned physical quantities changes using the radiation pre—treatment from the mineral processing improvement point of view are defined.
