在現代技术条件下,应当采用各种选矿方法处理矿石,以滿足国民經济多方面的需要。凡是妨碍了选矿任务加速完成的地区,显然就会使有色金屬和稀有金属的生产技术停滞不前。重介質选矿的現状便是这类例子当中的一个典型。苏联科学技术的广泛发展,对选矿的科学研究和选矿技术,起到了良好的促进作用。在今后的三年內,将要求选矿工作者解决下面一系列最重要的問題:綜合利用矿石原料;在科学研究与技术方面广泛的应用放射性同位素;采用多段选矿流程等等。随着对矿石原料资源的进一步掌握,将必然会提出一些有关选矿方法理論上的重大課題。由于使用放 Under the conditions of modern technology, various ore dressing methods should be used to deal with ore so as to meet various needs of the national economy. Any area that hinders the accelerated completion of the beneficiation task will obviously stall the production of non-ferrous metals and rare metals. The status of HM dressing is an example of this type of example. The extensive development of science and technology in the Soviet Union has played a good role in promoting scientific research and beneficiation technology in mineral processing. In the next three years, mineral processing workers will be asked to address the following series of most important issues: the comprehensive utilization of ore raw materials; the widespread application of radioisotopes in scientific research and technology; the adoption of multi-stage beneficiation processes and more. With the further mastery of the resources of ore raw materials, some major theoretical issues concerning ore dressing methods will inevitably come up. Because use put
