The fine grained ore microtextures limit the chalcopyrite liberation, and therefore the treatment of this ore achieves a lower copper recovery and lower concentrate grade. Finer grinding in the primary mills, and regrind circuit often improves flotation performance. For pyrrhotite dominant ore types, the chalcopyrite grain size is typically coarser, with less intergrowths of gangue minerals ...
