description The invention discloses ferro-molybdenum made of mixture powder and reducing agents. The mixture powder comprises, by weight, 21.0%-42.9% of molybdenum oxide powder, 0%-50.3% of iron oxide powder, 0%-33.2% of iron powder, 3.6%-23.5% of calcium molybdate and 3.2%-22.3% of industrial waste residue. In addition, the invention further discloses a method for preparing the ferro-molybdenum. According to the ferro-molybdenum and the preparation method thereof, carbon powder is adopted to serve as the reducing agents, the mixture powder and the reducing agents are mixed and then roasted at the temperature of not higher than 1600 DEG C to prepare the ferro-molybdenum, and pollutants such as nitrogen oxide and fluoride do not exist in the preparation process; the adaptability of the raw material formula is strong, compared with the traditional aluminothermy adopted to prepare the ferro-molybdenum, the quality adjustment and the quantity adjustment of the raw material formula have a good raw material adaptability.
