文摘

Ultrafine fractions produced by milling the ores were studied. Amounts of submicrometer and sub-5 μm particles reached 0.2 vol.% and 3 vol.%. The higher yields of the fines were found for Kingash ore and Norilsk valleriite ore. Colloids are mainly about 1 μm aggregates enriched in Mg silicates. Valleriite and chalcopyrite colloids are stable against oxidation and aggregation.
