The mineralogy, mineral chemistry and geological occurrence of metal sulfides, the major sources of world supplies of many metals, are reviewed. Emphasis is placed on the major sulfide minerals pyrite, pyrrhotite, mackinawite, galena, sphalerite and chalcopyrite, and the sulfarsenide mineral arsenopyrite.

Superconducting Hydrogen Sulfide
Chemistry – A European Journal, 2018AbstractThe recent discovery of superconductivity above 200 K in hydrogen sulfide under high pressure marks a milestone in superconductor research. Not only does its critical temperature Tc exceed the previous record in cuprates by more than 50 K, the superconductivity in hydrogen sulfide also exhibits convincing evidence that it is of conventional ...

Sulfides, Arsenides and Complex Sulfides (Sulfosalts)
2020This mineral class comprises most of the ore minerals. Many of them are opaque, i.e., they are non-transparent, even in thin sections that are not more than 20–30 µm in thickness, and show metallic lustre with different shades of colour.

Journal of Occupational and Environmental Medicine, 1979
Poisoning by hydrogen sulfide has been recognized as an occupational hazard for at least two centuries. The development of alternative sources of energy in North America may increase the incidence of this medical emergency in the future. Until recently, no specific antidote to sulfide was recognized.

Reviews in Mineralogy and Geochemistry, 2006
The past twenty years or so have seen dramatic development of the experimental and theoretical tools available to study the surfaces of solids at the molecular (“atomic resolution”) scale. On the experimental side, two areas of development well illustrate these advances.

Abstract Sulfur is one of the most common corrosive contaminants in high-temperature industrial environments and its presence can cause a number of problems, including sulfidation. This chapter describes the sulfidation behavior of a wide range of alloys as observed in three types of industrial environments.

Sulfide, Arsenide und komplexe Sulfide (Sulfosalze)
2009Diese Mineralklasse stellt den grosten Teil der Erzminerale. Die sich opak verhaltenden Minerale unter ihnen besitzen einen in der Farbe unterschiedenen Metallglanz. Die nichtopaken unter ihnen sind in dunnen Splittern durchscheinend, besitzen eine sehr hohe Lichtbrechung und zeigen Diamantglanz. Alle geben auf rauher Porzellanplatte einen diagnostisch
