Zincite
Zincite
is the
mineral
form of
zinc oxide
(
Zn
O
). Its
crystal
form is rare in nature; a notable exception to this is at the
Franklin
and
Sterling Hill Mines
in
New Jersey
, an area also famed for its many
fluorescent
minerals. It has a
hexagonal
crystal structure and a color that depends on the presence of impurities. The zincite found at Franklin Furnace is red-colored (mostly due to
iron
and
manganese
) and associated with
willemite
and
franklinite
.
