细筛工艺在赤铁石英岩选矿中应用显示出明显的技术经济效果,这已为选矿界所公认。随着细粒筛分工艺的发展,将其推广到锡选矿中已成为一个重要的研究课题。在云锡公司所进行的试验表明,有良好的效果。本文在该试验的基础上论述细筛在锡选矿厂中应用的几个问题,以期推广应用的研究。一、在锡选矿中应用的技术背景随着锡矿资源的开发利用,粗粒易选的锡矿日渐减少,细粒及超细粒嵌布而难选的锡矿日渐增多。以云锡公司为例,从1963年至1974年的十二年间,原矿中+74微米级别中的含锡率减少了11.75%,而-19微米级
Fine screening process in the hematite quartzite ore dressing application shows a clear technical and economic results, which has been recognized for the mineral processing sector. With the development of fine-grained screening technology, it has become an important research topic to extend it to tin beneficiation. The tests carried out at Yunxi have shown good results. Based on the test, this article discusses several problems of fine sieve used in tin concentrator, with a view to popularizing and applying the research. First, the technical background in the application of tin ore With the development and utilization of tin resources, coarse tin easily reduced tin ore, fine and ultra-fine embedded and difficult to pick tin deposits increasing. Taking Yun Tin Company as an example, from 1963 to 1974, the tin content in the ores at the +74 micron level decreased by 11.75% in the twelve years from 1963 to 1974, while the -19 micron level
