Abstract
Vanadium is a precious rare metal with very scarce resources available on earth�s crust. Due to
scarcity of deposits of vanadium and generation of large quantities of tailings produced by mining
and metallurgical activities, there is a need to find an economical way to recover vanadium from
secondary resources. This article brings out a comprehensive data collection of efforts placed
worldwide on extraction of vanadium from secondary sources like titaniferrous magnetite
(TMO), vanadium sludge of aluminium industry, other resources like effluents, spent catalysts,
LD slag, fly ash, oil sludge, spent vanadium catalysts, etc. Special emphasis is laid to the Bayer�s
sludge or vanadium sludge. The processes developed or in vogue for extraction of vanadium are
described in some detail, along with recent initiatives.
