摘　　要：1 引言 铼是一种稀有稀散金属元素，在地壳中含量极低。自然界中的铼主要以类质同相伴生在辉钼矿、铜钼矿中，焙烧钼精矿过程中产生的烟道灰也是回收铼的主要原料。金属铼具有硬度大、耐腐蚀、耐磨、熔点高、强度高以及良好的塑性等特点，A new method was developed for the determination of rhenium in molybdenum ores and flue dust by inductively coupled plasma atomic emission spectrometry（ICP-AES）-standard addition method.The method is simple and accurate,and it can solve the problem of analytical results easy to lower from industry standard method.Samples were treated with mixed acid,and under the condition of power 1150 W,atomizing pressure 30 psi,auxiliary gas flow 1.0 L/min,pump speed 100 r/min,rhenium in molybdenum ores and flue dust can be determined at analytical lines（nm） of 197.312（170）,227.525（148） The relative standard deviation（RSD） of the method was below 3.7%.Compared with other methods,the method is accurate.
