Based on analysis of estimation criteria for chemical resistance of nonferrous and rare metal minerals, it has been found possible to properly predict their reactivity prior to their mechanical activation reasoning from their energy density, bond uniformity and power characteristic of cations of oxygen compounds. The authors propose relationships for determination of structural changes in noble metal minerals under mechanoactivation, which ensure mineral opening under further hydrometallurgical treatment (temperatures under 100 ºC). These relationships are useful to pre-evaluate reactivity of minerals and, based on that, select effective mechanical activation conditions.
