Abstract

The processes of rebellious ore disintegration with regard to the surface properties of minerals and rocks are discussed. The methods are proposed for the experimental determination of surface tension of solids during evaluation of dispergating efficiency, and the calculation procedure of the surface layer thickness during ore disintegration is offered. The calculations of the fusion temperatures of nanoparticles obtained in nonconventional disintegration of rebellious ore are presented. The calculations are performed for the nanoparticles with possible content of the most metals from the periodic chart.

Keywords
