This is an article in the field of metallurgical engineering. Mangane-zinc spinel ferrite has been widely used in various fields due to its advantages of high permeability， high frequency and low loss. In order to make full use of Fe, Zn, Mn and other elements in electric arc furnace dust (EAFD)， Mn-Zn spinel ferrite was prepared by solid phase sintering method with alkali leaching zinc-containing EAFD as raw materials and MnSO4·H2O added. The effects of temperature， mass ratio (RZ/M) and pretreatment on the synthesis and magnetic properties of Mn-Zn ferrite were investigated by XRD, SEM-EDS and VSM. The results show that with the increase of reaction temperature，the speed of inter-grain merging in the Mn-Zn ferrite increases， the magnetic saturation induction and crystal grain size increase， and the coercivity decreases. When RZ/M changes to 1∶1.0，the magnetic saturation induction， coercivity and grain size increase. After pretreatment，the content of SiO2 in the EAFD decreases，and the magnetic saturation strength of the synthesized manganese-zinc ferrite increases. Therefore, after pretreatment with 2 mol/L alkali solution， the performance of manganzn-spinel ferrite synthesized at the condition of mass ratio 1∶1.0 and calcination temperature 1 100 ℃ is the best. Its saturation magnetic induction intensity (Ms) is 17.902 emu/g, and coercivity (Hc) is 3.21 kA/m.
