    Abstract: A system and method for recovering sulfur in a copper smelting process includes removing fine dust from high-concentration SO2 flue gas from a matte smelting furnace, introducing the flue gas into a fluidized bed carbothermic reduction tower to be reduced by a carbon-based reducing agent to obtain reducing gas, passing the reducing gas through a high temperature separator to separate down unsaturated powder coke contained in the reducing gas, and condensing the reducing gas to obtain sulfur. The saturated powder coke entrained in the reducing gas enters a desorption tower to desorb SO2 gas therein, and the desorbed powder coke enters a fluidized bed sulfur reduction tower to continue to participate in the reduction reaction. Part of the SO2 gas discharged from the desorption tower is discharged to the fluidized bed carbothermic reduction tower to produce sulfur, and the other part enters a desulfurization tower.
