摘　　要：采用Monte Carlo法产生矿粉样品的XRF谱,对30个矿粉样品的品位进行了分析,结果表明该方法能够对浓度值为百分之几及其以上的元素进行有效分析。还对影响分析效果的各种因素进行了讨论,结果表明学习谱的个数越多,标准样品浓度分布范围越广,分析结果越精确可靠。此方法分析速度快,可以用于对矿物品位进行在线分析。In this paper , by using the Monte Carlo method for producing mineral powder XRF spectra to test 30 samples of mineral grade , the results show that the method is capable for concentration values of several percent to tens of percent elements are tested .Various factors affect the analysis results have been discussed , results show that as the number of learning spectrum is more , and standard sample concentration range covers lager range , the testing results are more accurate and reliable .This method is fast for on-line testing of mineral grade .
