[0002] Soft ferrite is a material composed of metal oxides such as iron, nickel, manganese, and zinc, and is widely used in electronic devices such as sensors and transformers. The primary goal of recycling soft ferrite is to extract its metal components, particularly those with high economic value, such as iron, nickel, and manganese. Recycling soft ferrite is an efficient and important resource recovery process that effectively utilizes the metal resources in discarded electronic materials, reduces resource waste and minimizes environmental impact, thereby promoting sustainable development.
