Pentlandite phase relations in the Fe-Ni-S system and the stability of the pyrite-pentlandite assemblage.

Abstract

In the last decade geologists have made increasing use of phase equilibrium studies in synthetic systems to provide the fundamental data for the interpretation and understanding of the occurrence of minerals and mineral assemblages. The economic geologist has directed considerable study into the phase relations of the Fe-Ni-S system as a large number of the phases are found as minerals, which in some cases constitute important sources of nickel, iron and related metals.
