Nickel requires higher smelting temperatures (in the range of 1,350 °C [2,460 °F]) in order to produce an artificial nickeliron sulfide known as matte, which contains 25 to 45 percent nickel. In the next step, iron in the matte is converted to an oxide, which combines with a silica flux to form a slag.
Iron–nickel sulfide ((Ni,Fe)3S2) is one of the most promising bifunctional electrocatalysts for both the hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline media because of their metallic conductivity and low cost. However, the reported HER activity of (Ni,Fe)3S2 is still unsatisfactory. Herein, threedimensional selfsupported phosphorusdoped (Ni,Fe)3S2 ...
We report on the synthesis of ironnickel 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 αINS nanosheets show an even lower overpotential of 105 mV at ...
Nickel sulfide deposits are generally associated with iron and magnesiumrich rocks called ultramafics and can be found in both volcanic and plutonic settings. Many of the sulfide deposits occur at great depth. Laterites are formed by the weathering of ultramafic rocks and are a nearsurface phenomenon.
FeS adopts the nickel arsenide structure, featuring octahedral Fe centers and trigonal prismatic sulfide sites. Reactions. Iron sulfide reacts with hydrochloric acid, releasing hydrogen sulfide: FeS + 2 HCl → FeCl 2 + H 2 S  FeS + H 2 SO 4 → FeSO 4 + H 2 S. In moist air, iron sulfides oxidize to hydrated ferrous sulfate.

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.
Reaction of carbon monoxide (CO), hydrogen sulfide (H 2 S) and methanethiol CH 3 SH in the presence of nickel sulfide and iron sulfide generates the methyl thioester of acetic acid [CH 3COSCH 3] and presumably thioacetic acid (CH 3COSH) as the simplest activated acetic acid analogues of acetylCoA.
Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen nickel sulfides are known, including the mineral millerite, which also has the formula from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as catalysts.
Nickel is most often found in two types of ores, sulfides or laterites. While nickel laterite ores are more commonly found in the world, they are mined less than nickel sulfide ores, which make up the vast majority of current and historical production.
Russian nickel deposits are classified as nickel sulfide, which are the primary source of highgrade 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.

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.

The nickel–iron battery (NiFe battery) is a rechargeable battery having nickel(III) oxidehydroxide positive plates and iron negative plates, with an electrolyte of potassium hydroxide. The active materials are held in nickelplated steel tubes or perforated pockets.
It cannot be used in place of iron pyrites, although it has been mixed with that mineral as a source of sulphur. Sometimes, as in the Sudbury district, it carries nickel; but most of the nickel is in the form of distinct minerals, especially pentlandite a sulphide of iron and nickel that contains 22% of nickel.
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.

Nickel Deposits of North America By H. R. CORNWALL GEOLOGICAL SURVEY BULLETIN 1223 Geology, resources, and reserves of nickel sulfide and nickeliferous laterite deposits in 7 Provinces of Canada and 15 States of the United States UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON : 1966
The nickel(II) and iron(III) complexes of 1,1,5,5tetraisopropyl2thiobiuret were used as singlesource 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.
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 darkcolored streaks, and an igneous origin.
