Question

Calamine ore can be used to extract one of the following metals. This metal is:

विकल्प

• copper

Answer 1

Zinc

Calamine is a mineral ore composed mainly of zinc carbonate (ZnCO₃), a major source of pure zinc metal. The remaining choices do not match this source because copper is primarily obtained from copper glance (chalcopyrite), mercury is extracted from cinnabar, and aluminium is produced from bauxite.
