Abstract

Criteria of assessment of surface energy during the minerals disintegration are substantiated in the paper. Values of mechanochemistryactivation criterion of disintegration process are experimentally de fined for a number of gold-bearing ores of the Far Eastern region. It is established that directed changing of surface mineral characteristics makes possible prediction and optimization of technological parameters of ore crushing and Пѓ parameter (surface tension coefficient) and can be a regulated parameter of controlling of crushing process kinetics.
