Abstract
The influence of the state of contact surface of particles on mineral charge is examined. It is proved experimentally that polarity, mineral charge, and physical parameters of metal substrate of triboelectrizer can be altered by a directed action of external electrostatic field, which allows raising of electrostatic separation indices.
