磁选-阴离子反浮选工艺应用现状及展望

通过我国铁矿石资源与国外主要铁矿生产国铁矿石资源情况的对比,阐述我国铁矿石因具有储量大、品质差的特点必须加强选矿研究工作的重要性。介绍了国内一些选矿厂实施以“磁选-阴离子反浮选”选别工艺为核心的工艺流程的研究过程及效果,分析了“磁选-阴离子反浮选”选别工艺的特点,提出今后如何更加优化以“磁选-阴离子反浮选”选别工艺为核心的相关工艺流程和更好地在全国范围内推广这一工艺的建议。

Application Status of Magnetic Separation-Anionic Reverse Flotation Technology and Its Prospect

Through the comparision of China's iron ore resources with those of the main foreign iron ore producing countries, the importance of strenghthening the mineral processing research due to the charactistics of great reserve and poor quality of China's iron ore is expounded. The process and results of the research made in some domestic concentrators on the technological flowsheets with "magnetic separation-anionic reverse flotation" technology as the core are presented. The characteristics of the said core beneficiation technology are analysed and suggestions on how to better optimize the related technological flowsheets and to popularize this technology in a nationwide range are given.
