摘　　要：铁矿石中磁黄铁矿含量的化学分析方法有溴甲醇浸出法、硝酸浸出法和饱和溴水常温浸出法,为更好地选择合适的物相分析方法,本文对这三种方法进行了对比试验。结果表明,浸出温度对饱和溴水浸出法有影响,水浴加热浸出比常温浸出所得结果更好;硝酸浸出时间越长对硝酸浸出法结果影响越大,因此硝酸浸出法在应用时应严格控制浸出时间。Methods for chemical analysis of iron ore content of pyrrhotite leaching bromine methanol,Nitrate leaching,and saturated bromine water leaching at room temperature,in order to better select the appropriate phase analysis method,this paper carried out the three methods Comparative Experiment.The results showed that leaching temperature on leaching influential saturated bromine water bath heated leach results are better than normal leaching; nitrate leaching longer the result of the greater impact of nitrate leaching,nitrate leaching and therefore should be applied in strictly controlled leaching time.
