Oct 30, 2017· Nickel Sulfides: Higher grade, but rarer deposits that make up 37.5% of current production. Many laterite deposits are used to produce nickel pig iron and ferronickel, which are cheap inputs to make Chinese stainless steel. Meanwhile, nickel sulfide deposits are used to make nickel metal as well as nickel sulfate.
The recently announced LME nickel sulfate contracts under consideration are a strong indication that the nickel sulfate market and upstream nickel sulfide market are facing considerable growth.
Magmatic nickel sulfide deposits form when magmas derived from the Earth’s mantle ascend into the crust, in some cases reaching the Earth’s surface, and crystallise into iron-magnesium-nickel-rich mafic and ultramafic rocks containing concentrations of Ni-rich sulfide minerals.

Pentlandite is the most common terrestrial nickel sulfide. It typically forms during cooling of a sulfide melt. These sulfide melts, in turn, are typically formed during the evolution of a silicate melt. Because Ni is a chalcophile-like element, it has preference for (i.e. it "partitions into") sulfide phases.
The composition of the sulfide minerals can be expressed with the general chemical formula A m S n, in which A is a metal, S is sulfur, and m and n are integers, giving A 2 S, AS, A 3 S 4 and AS 2 stoichiometries. The metals that occur most commonly in sulfides are iron, copper, nickel, lead, cobalt, silver, and zinc, though about fifteen others enter sulfide structures.

Some of the hydrogen sulfide will react with metal ions in the water or solid to produce iron or metal sulfides, which are not water-soluble. These metal sulfides, such as iron(II) sulfide, are often black or brown, leading to the color of sludge. Pyrrhotite is a waste product of the Desulfovibrio bacteria, a sulfate reducing bacteria.

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.
Pig iron is a main component of stainless steel. Mohr added that nickel prices are expected to remain high until the second half of 2016, when new processing plants start pilot operations. As the Indonesian ore ban continues, many of nickel sulphide projects from around the world are thrust into the spotlight.

Thus, while nickel sulfide precipitates on the surface of initial iron sulfide, it is enriched with iron sulfide of high sulfur content which is hard for dissolution in water. Alongside sulfur content increase in pyrrhotite, higher acidity of the solution is required and also higher oxidizing potential for its dissolution is …

Jul 28, 2014· PYRRHOTITE: A "STRANGE" IRON SULFIDE During my recent trip to the AFMS-RMFMS show in Tulsa, Oklahoma (Blog July 21, 2014) I was on a quest to secure additional specimens that may contain nickel, especially pentlandite, an iron-nickel sulfide [(FeNi) 9 S 8.
We report on the synthesis of iron-nickel sulfide (INS) ultrathin nanosheets by topotactic conversion from a hydroxide precursor. The INS nanosheets exhibit excellent activity and stability in strong acidic solutions as a hydrogen evolution reaction (HER) catalyst, lending an attractive alternative to the Pt catalyst. The metallic α-INS nanosheets show an even lower overpotential of 105 mV at ...

One of the characteristics of magmatic sulphides is that the individual sulphide grains – like the orebodies as a whole – tend to be zoned having a more copper-rich top and nickel rich base. Thus magmatic sulphide grains are typically multi-phase being comprised of separate chalcopyrite (copper-rich), pyrrhotite (iron-rich) and pentlandite ...

Iron sulfide is primarily converted to oxide in roasting. When only about half the iron is oxidized during roasting, less nickel and copper sulfides are oxidized. In the case of partial roasting of nickel ore concentrate, it is mainly the pyrrhotite mineral, (Ni,Fe) 7 S 8 that is oxidized:
The Sulfide Class minerals comprise an economically important class of minerals. Most major ores of important metals such as copper, lead and silver are sulfides. Strong generalities exist in this class. The majority of sulfides are metallic, opaque, generally sectile, soft to average in hardness and they have high densities, black or dark-colored streaks, and an igneous origin.
Russian nickel deposits are classified as nickel sulfide, which are the primary source of high-grade nickel ore. According to Ahead of the Herd, 58 percent of global nickel production comes from nickel sulfide. The largest sulfide deposit in the country is found in Norilsk, which also happens to be the largest across the globe.
The nickel(II) and iron(III) complexes of 1,1,5,5-tetra-iso-propyl-2-thiobiuret were used as single-source precursors for the synthesis of nickel and iron sulfide nanoparticles, respectively, by thermolysis in hot oleylamine, octadecene, or dodecanethiol. Several combinations of different injection solvents and capping agents were used in the reaction mixture.

About 95% of all meteorites contain iron-nickel (FeNi) metal. "Iron-nickel" means that the metal is mostly iron but it contains 4-30% nickel as well as a few tenths of a percent cobalt. Iron-nickel metal in meteorites also has high concentrations (by terrestrial standards) of rare …

On Earth, nickel occurs most often in combination with sulfur and iron in pentlandite, with sulfur in millerite, with arsenic in the mineral nickeline, and with arsenic and sulfur in nickel galena. Nickel is commonly found in iron meteorites as the alloys kamacite and taenite. The bulk of the nickel mined comes from two types of ore deposits.
