苏联有色冶金工业部已着手研制和试生产各种X射线分选机。在开始阶段,工业上任何一种新的选矿方法的采用,选择有益矿物的类型是很重要的,以便在处理这种有益矿物时,能够得到最大的技术经济效益。这时,选择研究课题首先要考虑的是被选物料的研究程度,其次是必要设备的制造。对于辐射选矿法,最重要的性质之一,就是矿石的对比度。在有色金属圹石中,研究最多的是锡矿石的对比度。全苏矿物原料研究所,在锡石研究方面工作开展的最早,研究表明,锡矿石具有最大的对比度,能分出作为尾矿的矿块产率约占原矿量的60%,分选机选别粒度不小于25毫米的锡石是适宜的,尾矿中锡的品位为0.07%,这
Soviet Union Nonferrous Metallurgical Industry has embarked on the development and trial production of various X-ray sorting machine. In the initial stage, the introduction of any new beneficiation process in the industry, it is important to choose the type of beneficiary mineral so that the maximum technical and economic benefits can be obtained when dealing with this beneficial mineral. At this time, the first choice of research topics to consider is the degree of research selected materials, followed by the necessary equipment manufacturing. For radiation beneficiation, one of the most important properties is the contrast of the ore. In the non-ferrous metal stone, the most studied is the contrast of tin ore. All-Su Institute of mineral raw materials, cassiterite research work carried out the earliest studies have shown that tin ore has the maximum contrast, can be classified as tailings ore yield accounted for about 60% of the ore, sorting machine Cassiterite, which is not less than 25 mm in grain size, is appropriate, with a grade of tin in the tailings of 0.07%, which
