Sphalerite formula
An impure form known as sphalerite is the major ore from which zinc is obtained. This structure consists essentially of a FCC (CCP) lattice of sulfur atoms (orange) (equivalent to the lattice of chloride ions in NaCl) in which zinc ions (green) occupy half of the tetrahedral sites. As with any FCC lattice, there are four atoms of sulfur per unit cell, …Schalenblende - Banded form of Sphalerite and Wurtzite often associated with Galena (and sometimes Pyrite ). The term Schalenblende is occasionally incorrectly used as a synonym for Wurtzite. POLYMORPHS Wurtzite USES Sphalerite is the principle ore of zinc.

The two types have these features in common: a 1:1 stoichiometry of Zn:S. a coordination of 4 for each ion (4:4 coordination) tetrahedral coordination. Zincblende/sphalerite is based on a fcc lattice of anions whereas wurtzite is derived from an hcp array of ... Sphalerite is an ore—a mineral of economic value—that was once mined in southeastern Kansas for its zinc content. It is also called zinc blende, blende, blackjack, and mock lead. ... Chemical formula: ZnS (Zn = zinc, S = sulfur) Color: nearly colorless, but can be brown, yellow, black, or dark red due to impurities Streak: white to dark brownThe molecular or chemical formula of Zinc Sulfide is ZnS. It is obtained as a white or yellowish-white crystal. The sphalerite occurs as a greyish white crystal. ZnS is insoluble in water as well as denser than water. Naturally, it occurs as the mineral zinc blende which is also known as sphalerite. It is a mixture of zinc sulfide and iron.

In summary: these …Sphalerite can be found in many ore veins of sulfide minerals, commonly associated with galena and pyrite. Miners call sphalerite "jack," "blackjack," or "zinc blende." Its impurities of gallium, indium and cadmium make sphalerite a major ore of those metals. Sphalerite has some interesting properties. It has excellent dodecahedral … ….
