A novel recycling route using acid leaching, reduction, purification, co-precipitation and traditional ceramic process was applied to process the Mn-Zn ferrite wastes and prepare the corresponding high permeability soft magnetic product. Above 95% of Fe, Mn, Zn in the waste materials could be recycled in the form of Mn-Zn ferrite products through the hydrometallurgical route. The comprehensive properties of Mn-Zn ferrite prepared from wastes by this route have broader frequency characteristics, higher resistivity, lower loss coefficient and temperature coefficient as compared to the A102 product (Acme Electronics Corporation, Taiwan). Moreover, the cost of this recycling technology has economical advantage over the traditional ceramic process, which holds a promising industrial application.
采用酸浸、还原、净化、共沉淀和传统陶瓷工艺相结合的新工艺，对 Mn-Zn 铁氧体废料进行处理，制备相应的高磁导率软磁产品。通过湿法冶金路线，废料中 95%以上的 Fe、Mn、Zn 可以以 Mn-Zn 铁氧体产品的形式回收。与 A102 产品（台湾 Acme Electronics Corporation）相比，用这种路线从废料中制备的 Mn-Zn 铁氧体具有更宽的频率特性、更高的电阻率、更低的损耗系数和温度系数。此外，与传统陶瓷工艺相比，该回收技术具有成本优势，在工业应用方面具有广阔的前景。
