The invention discloses a process for extracting metallic antimony from antimony soot, which comprises the following steps: S1, leaching: mixing antimony soot with a sodium hydroxide solution, leaching, and carrying out liquid-solid separation; S2, oxidation: adding an oxidizing agent into the filtrate obtained after liquid-solid separation in the step S1, and carrying out liquid-solid separationoperation again after the reaction is completed, wherein the oxidizing agent comprises at least one of hydrogen peroxide, pure oxygen, ozone or sodium peroxide; and S3, reduction: the solid obtained after liquid-solid separation in the step S2 is antimony concentrate, adding a reducing agent into the antimony concentrate, then conducting reduction smelting, and obtaining metal antimony. Compared with the prior art, according to the scheme, after alkaline leaching, oxidation and reduction are conducted in sequence, high-purity metal antimony is prepared, meanwhile, multiple kinds of metal can be recycled step by step, the comprehensive recycling degree is high, and the process has the advantages of being low in production cost, environmentally friendly, good in economic benefit and the likeand is suitable for industrial large-scale production.
