Introduction: The most common zinc ore is sphalerite (zinc blende),
a zinc sulfide mineral. Zinc is refined by froth flotation of the
ore, roasting, and final extraction using electricity
(electrowinning). It is also
known asCalamine which is a historic name for an ore
of zinc.Zinc is
also used to make dry cell batteries, roof cladding and die
castings.
Zinc Ore:
Zinc is currently the fourth most widely consumed metal in the
world after iron, aluminum, and copper. It has strong anticorrosive
properties and bonds well with other metals. Consequently, about
one-half of the zinc that is produced is used in zinc galvanizing,
which is the process of adding thin layers of zinc to iron or steel
to prevent rusting.
