Table - 5 summarizes the conditions for
conducting the thermit reaction with different
vanadate compounds to produce ferrovanadium
analysing about 40 pct of vanadium content.
It can be seen that the alloy yields were higher
from 2 CaO. V205 than from 4CaO.V205, this
may be due to the higher lime content of 4Ca0.
V205 which may be adversely influencing the
yield. It may also be noted that increasing the
batch size of thermit reduction has a salutory
effect on the alloy yield. This is mainly attribu•
ted to improved utilization of thermal effect of
aluminothermic reduction.
