Interaction of Pentlandite, Chalcopyrite, and Pyrrhotine with Elementary Sulfur: II. Sulfidizing of Chalcopyrite

摘要

The results of the second part of the study into the sulfidizing of the main sulfide minerals of cop-per–nickel ores, namely, pentlandite, chalcopyrite, and pyrrhotine, by elementary sulfur are presented. The phase compositions of the sulfidizing products are examined by scanning electron microscopy and electron-probe microanalysis, and a mechanism is proposed for the sulfidizing of chalcopyrite under near-equilibrium conditions.
