Sphalerite chemical formula

Sphalerite reactivity varies as a function of composition; therefore the amount of acid formed varies. In general, oxidative dissolution of sphalerite does not produce acid but does release Zn 2+ (Eq. 13), but if Fe is the oxidant, acid is formed as shown in Eq. 14 (Abbassi et al. 2009). The reaction for Fe-rich sphalerite is also given in Eq.

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 ores are widely distributed throughout the world, although more than 40 percent of the world’s output originates in North America and Australia. The common zinc-containing minerals are the zinc sulfide known as zinc blende or sphalerite (ZnS), a ferrous form of zinc blende known as marmatite [(ZnFe)S], and a zinc carbonate known as calamine or smithsonite (ZnCO 3).
