Aspects of Norilsk Cu-Ni ore crystallization according to the data of the experimental study of Cu-Fe-S system
A study of the Cu-Fe-S melts crystallization products synthesized at low (0,13 Pa) and at high (5 GPa) pressure has been conducted. The study has shown that in contrast to the crystallization products of the Cu-Fe-S melts synthesized at pressure 0,13 Pa where the chalcopyrite solid solution (Cu,Fe)S...
