Abstract Thefludizedbedroastingofcoppersulfideconcentrateincludes threeforms：oxidationroasting，vulcanizationroasting， and semi-vulcanization roasting.Taking a copper sulfide concentrate with a copper grade of 60% and a sulfur grade of 17% in the DemocraticRepublicofCongoasthebject，afluidizedbedroastingsystem model wasconstructedusingMetCal softwarebasedon the parameters such as wind- ⋅to- ore ratio of 1.5m3/kg and oxygen excess coefficient of 1.2，to simulate the mass balance，heat balance， and gas composition under diffrent roasting conditions.The results indicate that the oxidation roasting （ S 750 A ） requires sulfur adding to maintain heat balance，the vulcanization roasting （650＼～670 C ）requires7.36 t/h cooling water to control overheating，The semi （20 vulcanization roasting （（700 C ） is the critical point of heat balance at 40% acidification rate（SO volume fraction of 0.719% ）. The calculation of furnacehearth area（ ⩾22m ），optimization of sulfur addition mode and design of the cooling system can provide data support for the engineering solution of the fluidized bed roaster.
