Selective Disintegration Justification Based on the Mineralogical and Technological Features of the Polymetallic Ores

Deterioration of mineralogical and physical characteristics mineral raw materials results in the formation primary task for comminution processes—reduction size ore to obtain a material with certain granulometric composition, which turn is achieved by overgrinding and, consequently, an increase energy costs. The work aimed justify possibility selective disintegration assemblages polymetallic ores various genesis at stage crushing based on in-depth investigation revealing interrelation mutual influence mineralogical-geochemical features, textural-structural technological properties. Structural textural features have been studied methods computed X-ray microtomography. Experimental theoretical investigations parameters materials, as well research using different types crushers, made it possible substantiate ores.
