摘　　要：目的:优选磁石的最佳炮制工艺。方法:以炮制时间、炮制温度、煅淬次数为考察因素,以水溶性铁、重金属(铜、镉、汞、铅)和有害元素(砷)的溶出量为评价指标,采用正交试验优选磁石炮制工艺。结果:最佳炮制工艺为600℃炮制0.5h,煅淬3次。结论:所选工艺合理、可行,可作为磁石的炮制工艺。OBJECTIVE：To optimize the processing technology of Magnetitum.METHODS：The orthogonal experiments were designed to optimize the processing technology of Magnetitum with processing time,temperature and calcining and quenching times as factors using the amount of water-soluble iron,heavy metals（Ca,Cd,Hg,Pb）and harmful elements（As） as index.RESULTS：The best processing technology was as follows：processing for 0.5 h at 600 ℃,calcining and quenching for 3 times.CONCLUSION：The optimized technology is reasonable and feasible,and it can be used for for the processing technology of Magnetitum.
