力程较疏水力长并随颗粒之间距离减小而急剧增加,它与疏水力联合,有利于颗粒间的团聚.显微镜观察和粒度测试表明:与单一疏水聚团的颗粒相比,磁-疏水联合聚团表观粒度大,比表面积小.磁场对于细粒软锰矿的回收及其与脉石的分离有利,磁化-浮选人工混合矿,在品位稍微提高的基础上,MnO2回收率提高23%.关键词:细粒软锰矿;磁化;疏水;聚团Magnetic-hydrophobic agglomeration...:To research the agglomeration behavior of fine pyrolusite in magnetic field, the magnetic- hydrophobic agglomeration was studied using the fine pyrolusite flotation in magnetic field. According......
to investigate the effects of particle size changing on the magnetism and agglomeration of magnetite particles, weak magnetic separation tests of magnetite were carried out stage by stage at different grinding... agglomeration force among the magnetite particles was also analyzed. The results show that there are some single magnetite and weak magnetic gangue ore in the primary grinding of magnetite, which can......
Preparation and magnetic property of multi-walled carbon nanotube/α-Fe2O3 composites CHEN Chuan-sheng(陈传盛)1, 2, LIU Tian-gui(刘天贵)3, CHEN Xiao-hua(陈小华) 2, LIN Liang-wu(林良武)1, LIU Qi...: In order to attain new functional nanomaterials with good magnetic property, multi-walled carbon nanotubes/hematite (MWNTs/α-Fe2O3) composites were synthesized using the co-deposition method. MWNTs......
