论文部分内容阅读
本文概述了世界各国选矿的有关文献。去年,在一般磨矿及自磨的大型磨矿设备的应用,及磨矿回路的自动化方面有了稳定的发展。在磁选方面,主要是研究极细粒及弱磁性物料的分选;而浮选则着重浮选理论的研究及新的大型浮选机的试制。在水冶方面,集中研究从非硫化矿中回收镍;水冶的基础理论研究胶微生物浸出稍有忽视。在布拉格举行的第九届国际选矿会议提出的有关团矿的论文证实,细粒精矿、特别是铁精矿的团矿,已成为选矿不可缺的一部分,将来,在这方面,将进行更多的研究工作。
This article outlines the relevant literature for beneficiation in various countries in the world. Last year, there was a steady development in the application of large-scale grinding equipment for general grinding and self-grinding, as well as the automation of grinding circuits. In the magnetic separation, the main research is very fine and weak magnetic material sorting; and flotation focuses on the flotation theory and the new large-scale flotation machine trial. In water and metallurgy, focus on the recovery of nickel from non-sulfide ore; watermelon basic theoretical study of micro-microbial leaching slightly neglected. The paper on gneiss proposed by the Ninth International Mineral Concentration Conference held in Prague confirms that the fines of fine-grained concentrates, especially iron concentrates, have become an indispensable part of beneficiation and in the future, more will be done in this area More research work.
