Abstract
Rare earth metals (REMs) play a significant role in the
manufacture of permanent magnets, fluorescent lamps,
catalysts, medicines, super alloys etc. Recently, China,
which controls 97% of world trade in REMs, imposed
restriction on its export. Consequently, the global demand
of REMs is escalating and is expected to exceed the supply
by 40,000 tonnes annually. Present review paper reports the
flow-sheets of commercial processes based on pyro-hydro
and hybrid techniques as well as systematic research for
process development to recover REMs from primary and
secondary resources. This review paper also reports the
recommendation and future prospective to fulfill its
demand and supply gap keeping in view environmental prospective.
