The invention provides a method for enriching antimony from antimony oxide ore. A device adopted by the method comprises a side blowing oxygen-rich volatilizing furnace. The method comprises the stepsthat the antimony oxide ore is smelted in the side blowing oxygen-rich volatilizing furnace to obtain antimony smoke gas. The sublimation temperature of antimony oxide is low so that by means of themethod that the antimony oxide ore is smelted in the side blowing oxygen-rich volatilizing furnace, the antimony oxide can be converted into the smoke gas as much as possible, thus the loss of the antimony oxide is advantageously reduced, and the recovery rate of antimony is improved advantageously accordingly. Meanwhile special treatment does not need to be conducted on a reaction raw material, and the method for enriching antimony from the antimony oxide ore has the advantages that the technique is simple and the cost is low. 本发明提供了种从锑氧化矿中富集锑的方法。该方法采用的装置包括侧吹富氧挥发炉，方法包括：将锑氧化矿在侧吹富氧挥发炉中进行熔炼，得到锑烟气。由于氧化锑的升华温度较低，因而将锑氧化矿在侧吹富
