摘　　要：中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,这不仅浪费了大量的资源,还严重污染了环境。根据废干电池和钛白废硫酸的特点,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、氟化等工序净化除杂后,采用共沉淀法制取锰锌铁氧体。产品初始磁导率达8 000 H/m以上,杂质质量分数小于1×10-4。该工艺以废治废,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 China,as well as large amounts of waste sulfuric acid from titanium dioxide industry.This not only wastes a lot of resources,but also seriously pollutes the environment.According to the characteristics of waste dry battery and titanium dioxide waste sulfuric acid,the technology using titanium dioxide waste sulfuric acid to leach waste dry battery has been studied.Through purifying procedures,such as vulcanization,oxidation heating,substitution,hydrolysis,and fluorination,manganese zinc ferrite was prepared by coprecipitation method.The results of test showed that its initial magnetic permeability was more than 8 000 H/m and the mass fraction of impurity was less than 1×10-4.This process is treating waste by waste.The main ingredients in the waste do not need to separate from each other,which can be used to prepare higher-value added manganese zinc ferrite,directly and a small amount of impurity elements can be also removed and disposed through purification.
