The incineration slag of circuit board was doped with different proportions of copper concentrate, and then calcined at a high temperature to prepare oxygen carrier. The effects of doping amount of copper concentrate and calcination temperatures on the phase composition and morphology, as well as the oxygen absorption and desorption performance of the prepared oxygen carrier were all explored. The results indicate that CuFe2O4 is the main phase of the oxygen carrier, the formation of which can be improved by increasing the doping amount of copper concentrate and calcination temperature; the prepared oxygen carrier exhibits excellent lattice oxygen transfer capability; the mass weight of oxygen carrier in an air atmosphere increases by about 3% due to oxygen absorption, while the mass weight in a nitrogen atmosphere decreases by about 4% due to oxygen desorption.
