PURPOSE: A manufacturing method of ferromolybdenum is provided to save manufacturing cost by using C instead of the Al and Si as a reducing agent and simplifying a manufacturing process of the Fe-Mo by directly reducing the Fe-Mo with mixing the moS2 which is a starting material and a ferric oxide. CONSTITUTION: A manufacturing method of ferromolybdenum comprises the following steps. (S100) Molybdenite (MoS2), Fe powder, a hematite (Fe2O3), a reducing agent, a binder and filler are mixed and a pellet is manufactured. (S200) A heat reduction reaction is performed in the decompressed state about the pellet. And (S300) hydrogen gas (H2) is blown in and exhausted and removes sulfur (S) from the pellet. The reducing agent is the carbon (C). The binder is more than one from gelatines, sugars, molarsses and Na2SiO3. The filler is more than one from wood flour, a fiber and particles. In the step (S200), the reducing reaction temperature is 1360-1400°C. In the step (S200), the decompression state is 10-1 torr. In the step (S300), the hydrogen gas (H2) is blown in and exhausted at 298-300°C for 3 hours.
