• Pentlandite an overview | ScienceDirect Topics

    Pentlandite is the principal host for the bulk of the cobalt in the Sudbury ores (Naldrett, 1961), and there is a range in Ni/Co ratio depending on whether the pentlandite was formed in a contact or footwall environment (Lightfoot, 2015). Some cobalt exists in solid solution in pyrrhotite, and the Ni/Co ratio of pyrrhotite + pentlanditerich ...
