　　我国每年报废上百万吨的废干电池，钛白工业也会产生大量的废硫酸，这不仅浪费了资源，还严重污染了环境。根据废干电池和钛白废硫酸的特点，本工艺研究用钛白废硫酸浸出废干电池，通过硫化、氧化加热、置换、水解、氟化等净化除杂后，采用共沉淀法制取锰锌铁氧体，产品初始磁导率达8000以上，杂质质量分数小于10-4。该工艺采取以废治废，废物中的主要成分不需相互分离即可制取高附加值的锰锌铁氧体，少量的杂质元素可通过净化脱除并进行处置。

Every year millions of tons of waste dry battery are scrapped in our country, and large amount of waste sulfuric acid from titania industry is produced, which not only wastes a lot of resources, but also seriously pollutes the environment. According to the characteristics of waste dry battery and waste sulfuric acid from titania industry, waste dry batteries are soaked in waste sulfuric acid, and then the mixture are purified through process of vulcanization, oxidation heating, substitution, hydrolysis and fluoridization, at last the manganese zinc ferrite is prepare by coprecipitation method. The result of test shows that its μi is more than 8 000 and the mess fraction of impurity is less than 10-4. This process treats waste using waste. The main ingredients of waste do not need to separate, and higher-value manganese zinc ferrite can be prepared. Additionally, a small amount of impurity element can be removed and disposed through purification.
