意大利卡利亚里大学在矿石电选方面的研究工作开始于六年以前,所得到的结果发表在一系列文章中。最近我们把注意力集中在下述两个问题上,电选的进一步发展有赖于这两个问题的解决: 1.细磨物料的选别; 2.对表面电导率或体积电导率差别不大的矿粒在电场中行为的分析。
The research on electrocution of ore at Cagliari University in Italy began six years ago and the results were published in a series of articles. Recently, we have focused our attention on the following two issues. The further development of the power election depends on the resolution of these two issues: 1. Selection of finely ground materials; 2. Little difference in surface conductivity or volume conductivity Analysis of Mineral Particles in Electric Field.
