Sphalerite is a
sulfide mineral with the
chemical formula (Zn, Fe)S. It is the most
important ore of zinc.
Sphalerite is
found in a

structural polymorph form of
sphalerite. The iron
content is
variable up to
eight percent. It is
trimorphous with
matraite and

where it
mainly occurs as the
mineral sphalerite.
Although this
