旋流器自五十年代在我国冶金矿山用作分级设备以来,已得到广泛的应用。特别是在锡、钨的重选厂,已成为细粒级分级、脱泥的关键性设备。近年来,国外对采用短锥旋流器作为细粒级金矿的选别设备方面作了大量的研究工作,取得了较好的效果,然而,国内在这方面的研究却很少。为了发展我国的选金工业,我们用短锥旋流器对黑河金矿细粒级部分进行了工业性选别试验,取得了初步成果,现将有关情况 Cyclone since the 1950s in China’s metallurgical mine used as a grading equipment, has been widely used. Especially in tin, tungsten re-election plant, has become a fine-graded grading, mud off the key equipment. In recent years, a great deal of researches have been done abroad on the selection of short cone hydrocyclones as a sorting equipment for fine-grained gold deposits, and good results have been achieved. However, there are few studies in this area in China. In order to develop the gold industry in our country, we used the short cone hydrocyclone to carry on the industrial sorting test to the fine fraction of Heihe Gold Mine, and achieved initial results.
