The mineral system characteristics of the Sudbury Ni-Cu-Co-PGE sulfide ore deposits. Peter C. Lightfoot, in Nickel Sulfide Ores and Impact Melts, 2017 Cobalt. 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 …

Pentlandite is both an individual mineral, and the name of a mineral group. The Pentlandite group is composed of rare sulfides that have similar chemical structures, with Pentlandite being the most prominent member of the group. Pentlandite is named in honor of Joseph Barclay Pentland (1797–1873), a natural scientist from Ireland who first …

Two faces on this hefty ore specimen are sawed. The polished face accentuates the rich bronze-yellow color saturation of the microcrystalline ore and the included xenoliths of dark and light minerals are fine accessories. Pentlandite specimens of this richness and quality are rare and are seldom available.

Pentlandite is the most common terrestrial nickel sulfide mineral formed from immiscible sulfide-silicate melts under normal mantle and crustal conditions. Nickel, being a chalcophile element, prefers to inhabit a sulfide phase versus a silicate or oxide phase within most terrestrial lithochemical systems (a few exceptions exist in unusual ...

The flotation kinetics of principal ore minerals is shown in Fig. 2.As is evident, the principal ore minerals—pentlandite and chalcopyrite—are characterized by greater floatability than the others and, owing to this, practically all the opened grains and rich aggregates of these minerals pass to the concentrate of between-bath flotation.

The pentlandite in the Timmins ore was shown to be extremely sensitive to the lime system, remaining completely depressed at a collector dosage that can float the pentlandite in the Sudbury ore very well.
