摘　　要：辐射分选是利用含有用元素的矿块和废石块在受照射后反应的差别或其本身放射性的差别而将矿石与废石分开的一种分选方法。除去大块废石后可以降低运输、破碎、磨矿和进一步处理的费用，所以受到选矿工作者的重视。众所周知，在电磁波谱范围内的各种射线（无线电波、可见光、X射线，γ射线等）都可作为照射源而为辐射分选不同矿石时所利用。本文介绍了近年来报道的数种分选机及对铀、金、金刚石等矿石的分选指标。Radiometric sorting is a separation method in which the natural radioactivity of ores and their different reaction after being radiated are used for separating useful minerals and waste rocks. After rejecting the waste rocks the cost of transportation,crushing,grinding and next step treatment can be reduced,so mineral processing engineers pay great attention to such kind of sorting. It is known that for sorting different ores,all the rays of electromagnetic waveband (radiowave,natural light, X-ray,γ-ray and so on)can be used as the sourecs of irradiation.Based on the recently published data, this paper presents several sorting machines and some sorting targets of uranium,gold,diamond and ther ores.
