摘要
现在工业上铁矿石的全分析主要以熔融片法进行荧光确定砷、磷、钙、硅的含量,管式炉法测定硫含量,以及化学滴定全铁三个操作确定一个铁矿石主要成分。其中熔融荧光法操作比较耗时,在生产量逐渐增大的同时,化验室的检验量也在逐渐增大,相对费时的熔融荧光法已经无法适应日益增长的生产需要。本文确认了X射线荧光粉末压片法分析铁矿石的工作条件,其分析主量TFe成分RSD≤0.152%,SiO_2成分RSD≤0.897%,P成分RSD≤4.464%。该方法快速、简便,结果准确可靠。
Nowadays wide analysis of iron ore usually use melting tablets to do fluorescence in order to determine arsenic,phosphorus,calcium,silicon,but it is time-consumed.With the productions increase,the quality of laboratory testing also gradually increase.So it is not the most suitable detection method.A method of determination of iron ore by XRF-pressing method was described.The RSD of TFe is less than 0.152%,the RSD of SiO_2 is less than 0.897%,the RSD of P is less than 4.464%.Results proved that this method is precise,quick and easy operation.
