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
variety of deposit...

galena PbS was
mined as an ore of lead, and the
sulphides pyrite FeS2 and
sphalerite ZnS were also present. Many
carbonates occur there,
including ankerite...
- 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...
-
structural polymorph form of
sphalerite. The iron
content is
variable up to
eight percent. It is
trimorphous with
matraite and
sphalerite. It
occurs in hydrothermal...

occurs in near-opaque
minerals with very high
refractive indices, such as
sphalerite, cinnabar, anthracite, and cuprite.
Vitreous minerals have the lustre...

often showing octahedral forms. It is
often ****ociated with the
minerals sphalerite,
calcite and fluorite.
Galena is the main ore of lead, used

rather as gallium(III)
compounds in
trace amounts in zinc ores (such as
sphalerite) and in bauxite.
Elemental gallium is a

- by-product
during the
processing of the ores of
other metals,
chiefly from
sphalerite and
other zinc
sulfide ores.

typically a metal.
Examples are
cinnabar (HgS), an ore of mercury;
sphalerite (ZnS), an ore of zinc; c****iterite (SnO2), an ore of tin; and colemanite...
