Antimony sulfide concentrate oxygen-enriched melting tank melting method

The invention discloses an antimony sulfide concentrate oxygen-enriched melting tank melting method. For solving problems of high pollution and high energy consumption of existing blast furnace volatilization melting technologies, and the impossibility of practical industrialization of existing oxygen-enriched melting tank melting technologies, the antimony sulfide concentrate oxygen-enriched melting tank melting method provided by the invention comprises the steps that: (1) material blending is carried out, wherein antimony concentrate limestone, quartz sand and iron ore are blended; (2) the blended material is granulated; (3) melting is carried out, wherein antimony sulfide is subjected to a volatilization or oxidation reaction and enters flue gas, and partial antimony sulfide enters melting slag through the oxidation reaction; (4) smoke dust recovery is carried out; (5) antimony oxide in the melting slag is reduced into metal antimony; (6) crude antimony and reduction slag are discharged in a stratified ma
