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 (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.
Wurtzite is a zinc and iron sulfide mineral with the chemical formula (Zn,Fe)S, a less frequently encountered structural polymorph form of sphalerite. The iron content is variable up to eight percent. [5] It is trimorphous with matraite and sphalerite. [2] It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite ...

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 ...

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. A useful property of ZnS is its phosphorescence.
For the ores Cu 2 S and ZnS , balanced equations for the roasting are: 2 Cu 2 S + 3 O 2 → 2 Cu 2 O + 2 SO 2 2 ZnS + 3 O 2 → 2 ZnO + 2 SO 2. The gaseous product of sulfide roasting, sulfur dioxide (SO 2) is often used to produce sulfuric acid. Many sulfide minerals contain other components such as arsenic that are released into the environment.
