Morphometric parameters of sulphide ores as a basis for selective ore dressing

To assess the possibility of selective disintegration and reduction overgrinding hard-to-reproduce ores, optical microscopic X-ray microtomographic studies were carried out quantitative characteristics morphological parameters disseminated rich cuprous ore samples from Norilsk-type Oktyabrsky deposit identified. Among most informative are area, perimeter, edge roughness, sphericity, elongation average grain spacing for copper-nickel ores; roughness ores. The studied characterized by increased values dispersion in zones, which is especially important fine-grained difficult to diagnose methods. Three-dimensional modelling internal structure sulphide mineralisation was using computed microtomography, allows observation grains, aggregates their distribution total rock volume interrelationship with each other. evaluation pore space computer microtomography made it possible compare results obtained strength rocks including those on different types crushers. structural-textural analysis size minerals allow us evaluate applying crushing at various stages preparation
