11th International Multidisciplinary Scientific GeoConference SGEM2011, www.sgem.org, SGEM2011 Conference Proceedings/ ISSN 1314-2704, June 20-25, 2011, Vol. 1, 1091-1094 pp
Criteria of assessment of surface energy during the minerals disintegration are substantiated in the paper. Values of mechanochemistryactivation criterion of disintegration process are experimentally defined 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 σ parameter (surface tension coefficient) and can be a regulated parameter of controlling of crushing process kinetics.
Keywords: ore-bearing ores, disintegration, surface energy, chemo-mechanical activation, optimization criterion.
