Vanadium bearing slag analysing 16.5%
V205, 50% FeO, 16% Si02, 6% Cr203 and 8%
Mn0 was obtained from the pilot plant of MJs.
Visvesvaraya Iron and Steel Ltd. (VISL) during
three stage processing of titaniferous magnetite
ore containing about 1 pct V205. In the first
stage, the ore is carbothermically smelted to
yield vanadium bearing pig iron. In the second
stage the metal is blown in a converter to
generate a slag containing about 14 pct V205
and 57 pct iron oxide. In the third stage the
slag is reduced once again with carbon to generate
enriched vanadium bearing slag.
