Graphite is like diamond, It is a form of native carbon crystalline with its atoms arranged in a hexagonal structure that is opaque and dark gray to black.It occurs as hexagonal crystals, flexible sheets, scales, or large masses. It may be earthy, granular, or compact. Graphite forms from the metamorphism of carbonaceous sediments and the reaction of carbon compounds with hydrothermal solutions.
The Homestake Mine was a deep underground gold mine (8,000 feet or 2,438 m) located in Lead, South Dakota.Until it closed in 2002 it was the largest and deepest gold mine in North America.The mine produced more than forty million troy ounces (43,900,000 oz; 1,240,000 kg) of gold during its lifetime. This is about 70.75 m 3 or a volume of gold roughly equal to 18 677 gallons (a cube with each ...

Pentlandite is an important ore of nickel. However, it does not produce good crystals and is generally only found in massive form. It is commonly associated with other sulfides such as pyrite, chalcopyrite and pyrrhotite in basic igneous rock intrusions. These sulfide ore bodies are probably produced through magmatic segregation.
Pentlandite definition is - a bronzy yellow mineral that is an isometric nickel iron sulfide and the principal ore of nickel.
Pentlandite. Pentlandite is an iron - nickel sulfide, (Fe,Ni) 9 S 8. Pentlandite usually has a Ni:Fe ratio of close to 1:1. It also contains minor cobalt. It is named after the Irish scientist Joseph Barclay Pentland (1797-1873), who first noted the mineral. Pentlandite forms isometric crystals, but is normally found in massive granular aggregates.
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 identified this mineral.

Comments: Pentlandite resembles other yellowish metallic minerals and is cut by collectors as a curiosity. The cut stones are quite attractive but too soft for hard wear. Pentlandite is usually intimately intermixed with pyrrhotite and chalcopyrite in Canadian ore bodies, creating an interesting, multicolored metallic appearance.

Pentlandite Group. Cobaltpentlandite-Pentlandite Series. Pentlandite is a rather pale brassy yellow metallic sulphide, one of the most important nickel ores, and a primary mineral in many ultramafic rocks.
Pentlandite, nickel iron sulphide, is the principal ore for nickel. Pentlandite is found in the form of massive granular aggregates. It appears as a brassy gold-colored mineral, having similarities in characteristics to other sulfide minerals like pyrrhotite and chalcopyrite.
Pentlandite (Fe9Ni9S16) Pentlandite [Nickel and nickel compounds] 53809-86-2. Molecular Weight. 1543.9 g/mol. Component Compounds.
A silvery, hard, ductile, ferromagnetic (easily magnetized) metallic element used in alloys, in corrosion-resistant surfaces and batteries, and for electroplating. M ost nickel compounds are blue or green. Nickel occurs sparingly in nature in minerals such as pentlandite and niccolite. It is present in most meteorites.
Originally named cobalt pentlandite (two words) in 1959 by O. Kuova, Maija Huhma, and Yrjö Vuorelainen, for its cobalt content and relation to pentlandite. The name was later changed to a single word by the International Mineralogical Association (Burke 2008).
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 + pentlandite-rich ...
