The results of various methods of studying structural and texture characteristics, physical and mechanical properties determining the liberation of ore minerals are presented in the article. They allow to estimate the content of ore minerals in them, to analyze particle size distribution and spatial distribution of their grains, etc. These data provide more detailed information on the strength properties of ore and the possibility of selective comminution at the stage of study and design of beneficiation schemes. The analysis of mineralogical and geochemical composition as well as the results of technological research have shown that investigated copper-nickel ores satisfy the criteria of selective comminution.
