金刚石的分选工艺是由不同的选别方法组成的。金刚石的多种物理、化学性能被用作各种分选方法的依据。目前采用的分选方法有淘洗盘、跳汰、重介质、油选、X光电分选、电选、磁选、表层浮选、泡沫浮选、选择性磨矿和熔融等方法。近年来,人们对重介质分选、油选和X光电分选进行了较多的研究。现仅就上述三种选矿技术的新发展加以介绍 The diamond sorting process is composed of different sorting methods. Various physical and chemical properties of diamond are used as a basis for various sorting methods. Currently used sorting methods are panning pan, jig, heavy media, oil election, X-ray sorting, electricity election, magnetic separation, surface flotation, froth flotation, selective grinding and melting and other methods. In recent years, there have been many researches on heavy medium sorting, oil selection and X-ray sorting. The new development of the above three mineral processing technologies is now introduced
