We have studied patterns in the influence of O/C in the charge on the content of C, O 2 , and Mo in metallized molybdenum concentrate after different temperatures of thermal treatment. it was determined that O/C at 1.75‒2.00 in the charge after treatment at 1,223–1,423 K provides for the content of Mo in metallized molybdenum concentrate at 74.6–78.0 % by weight. The content of C and O 2 was 0.5–2.0 % by weight, and 0.6–5.5 % by weight, respectively. At O/C in the charge at 2.50, the products of reduction after heat treatment at 1,323 K consisted of Mo and MoO 2 . The residual molybdenum-containing oxide component is due to the insufficient amount of a reducing agent. The presence in the phase composition of carbide Mo 2 C together with Mo was found at O/C in the charge at 1.33, indicating a certain excess of the carbon reducing agent. The most favorable conditions for reduction were ensured at O/C in the charge at the level of 1.83 with a transition of most of the oxides to the metal phase of Mo. We have obtained a spongy structure of the metallized product, which ensures an increased rate of dissolving the obtained molybdenum-containing additive in a liquid metal at alloying. We did not identify in the phase composition any compounds susceptible to sublimation, which predetermines a reduction in the losses of Mo when using an alloying additive.
