PURPOSE:To provide a method for producing powdery starting material for soft ferrite by which yield is enhanced by reutilizing discharged powder, the generation of harmful corrosive gas due to gaseous chlorine is prevented, safety in operation and no corrosion of a stirrer are ensured and safety and prolonged service life can be ensured for facilities. CONSTITUTION:Discharged powder made of material retained in a roasting equipment system is dissolved in hydrochloric acid in the presence of metal zinc or metal manganese and the resulting soln. is mixed with chlorides of metals constituting ferrite. |
