The reaction of reduction of Mo0

3

with different adding method by 500 g Fe-1. 80% 〜3. 50% [ C

]

melts with nitrogen protective atmosphere at 1 300 ~ 1 500 °C has been studied. Results show that at W 1 400 °C with free slag condition

the reduction rate of Mo0

3

by feeding MoO

3

powder is faster than that by adding Mo0

3

pellet

and the [C

]

in melt is main factor to reduce MoO

3

as the [C

]

in melt is about 2%

then yield of molybdenum is up to 96% ； with slag condition

the effect of temperature of melts on reduction reaction of Mo0

3

is larger

with increasing temperature

the reduction rate of Mo0

3

increases

and the yield of molybdenum in 1.80% [C

]

melt is up to 100% at 1 500 °C. As the steel bearing Mo is melted by converter

to feed powder MoO

3

in hot metal

then form the slag with nice

flowability is available to fast reduce MoO

3

and increase yield of Mo.
