The invention provides an antimony concentrate smelting system. The antimony concentrate smelting system comprises a bottom-blowing oxidation smelting device, a reduction smelting device and an oxygen-rich volatilization device, wherein the bottom-blowing oxidation smelting device is provided with a first feed inlet and a first antimony-bearing slag outlet; the reduction smelting device is provided with a second antimony-bearing slag outlet and a first metal phase outlet; the first antimony-bearing slag outlet communicates with the reduction smelting device through a first antimony-bearing slag conveying channel; and the oxygen-rich volatilization device is provided with a second metal phase outlet and a waste slag outlet, and communicates with the second antimony-bearing slag outlet through a second antimony-bearing slag conveying channel, and the second metal phase outlet is used for discharging metal antimony products. The oxidation smelting can be performed at a low temperature in the bottom-blowing oxida
