The invention provides an extraction method for antimony metal. The extraction method comprises the step that volatilization smelting is conducted on antimony-containing materials. The volatilizationsmelting step is conducted in an electric heating volatilization device. Volatilization smelting is conducted on the antimony-containing materials in an electric heating mode. Air blasting and fuel burning are not needed in the whole volatilization smelting process, thus the smoke quantity can be lowered greatly, and then the concentration of SO2 in smoke can be increased greatly. The produced high-concentration SO2 smoke can be recycled through acid making, and thus the problems that in a traditional blast furnace volatilization process, low-concentration SO2 cannot be recycled, and consequently pollution occurs are solved. Meanwhile electric heating efficiency is high, and the molten state of slag can be always kept during fluctuation of the type of the slag. The use quantity of matchedflux can be reduced, the slag quantity is reduced, the high volatilization rate of antimony sulfide and antimony oxide can also be increased, and thus environmental protection, energy conservation, increase of the recycle rate and other comprehensive benefits are achieved.
