.... The Co-Fe and Co-As sulfide minerals are most suitable for Co and Ni recovery by a hydrometallurgical autoclave process, with potential pretreatment of cobaltiferous pyrite/arsenopyrite in an inert-atmosphere roaster, in new domestic or anticipated international facilities. The ICB is the second largest...

... chalcopyrite and locally minor tennantite replace fine-grained pyrite, barite, and carbonate. Cobalt occurs in early framboidal, cobaltiferous pyrite. Mineralizing fluids apparently moved up the synsedimentary normal fault and vented onto the sea floor. Structural basins in the hanging wall of the basin...

Two generations of pyrite have been recognized: the fine-grained stratiform variety and the coarse-grained epigenetic variety. Most of the cobalt is contributed by the epigenetic variety of pyrite ( Nash...
