Zinc sulfide (or zinc sulphide) is an inorganic compound with the chemical formula of ZnS. This is the main form of zinc found in nature, where it mainly occurs as the mineral sphalerite . Although this mineral is usually black because of various impurities, the pure material is white, and it is widely used as a pigment.
Sphalerite is a sulfide mineral with the chemical formula (Zn, Fe)S. [5] It is the most important ore of zinc.Sphalerite is found in a variety of deposit types, but it is primarily in sedimentary exhalative, Mississippi-Valley type, and volcanogenic massive sulfide deposits.
Zinc sulfide, ZnS, crystallizes in two closely related structures, the zincblende crystal structure and the Wurtzite crystal structure, which are common structures of compounds with the formula MA. Both Zn and S are tetrahedrally coordinated by the other ion.
Zinc sulfide (ZnS) is used in luminescent pigments such as on the hands of clocks, X-ray and television screens, and luminous paints. [151] Crystals of ZnS are used in lasers that operate in the mid-infrared part of the spectrum. [152] Zinc sulfate is a chemical in dyes and pigments. [148] Zinc pyrithione is used in antifouling paints. [153]
2–4 (generalized formula) Persian blue: made by grinding up the mineral Lapis lazuli. The most important mineral component of lapis lazuli is lazurite (25% to 40%), a feldspathoid silicate mineral with the formula (Na,Ca) 8 (AlSiO 4) 6 (S,SO 4,Cl) 1–2. Cobalt pigments. Cobalt blue (PB28): cobalt(II) aluminate. Cerulean blue (PB35): cobalt ...
Sphalerite, which is a form of zinc sulfide, is the most heavily mined zinc-containing ore because its concentrate contains 60–62% zinc. [14] No significant deposits of cadmium-containing ores are known. Greenockite (CdS), the only cadmium mineral of importance, is nearly always associated with sphalerite (ZnS). This association is caused by ...
That was the No. 1 thing that happened tonight. Some things are bigger than ball. This was one of those moments." Belyeu's home run ball was caught by a young fan and returned to the team, ...
The most common zinc concentrate processed is zinc sulfide, [1] which is obtained by concentrating sphalerite using the froth flotation method. Secondary (recycled) zinc material, such as zinc oxide, is also processed with the zinc sulfide. [2] Approximately 30% of all zinc produced is from recycled sources. [3]
