J. Cent. South Univ. (2016) 23: 1058-1065 DOI: 10.1007/s11771-016-0355-x Flotation of a new chelate collector on fine refractory iron ore-containing carbonate WANG Ting-xia(王婷霞)1, ZHU Yi-min(朱一民)2... University Press and Springer-Verlag Berlin Heidelberg 2016 Abstract: A suitable and efficient flotation collector at normal atmospheric temperature for Donganshan iron ore was developed. A new......
flotation[3]. Instead, kerosene, vapor oil, fuel oil, transformer oil and other hydrocarbons are often employed in direct flotation of molybdenite or in molybdenite-copper separation[4-7]. A typical... and iron sulfides in the flotation separation of molybdenite concentrate has been practiced [1, 8-10]. However, sodium silicate is used as the dispersant and depressant to depress the flotation of gangue......
Effect of surface dissolution on flotation separation of fine ilmenite from titanaugite ZHU Yang-ge, ZHANG Guo-fan, FENG Qi-ming, YAN Dai-cui, WANG Wei-qing School of Resources Processing and Bioengieering, Central South University, Changsha 410083, China Received 8 June 2010; accepted 21 September 2010 Abstract: The influence of surface dissolution on flotation separation of fine ilmenite......
bubble time, and pressure of the circulating pump during the sorting process were investigated and optimized to improve the flotation efficiency. On the basis of these parameters, continuous separation...Semi-industrial experimental study on bauxite separation using a cell?column integration processNing-ning Zhang1,2,Chang-chun Zhou1,2,Long-fei Cong1,2,Wen-long Cao1,2,You Zhou1,21.

)Abstract:Flotation experiments were performed to investigate the separation of muscovite and quartz in the presence of dodecylamine (DDA), tallow amine (TTA) and dodecyltrimethylammonium bromide.... The results reveal that the separation of muscovite from quartz is feasible at strong acid pulp condition using amine collectors. TTA and DTAC show poorer collecting ability for flotation of the two minerals......
Froth flotation is the most important mineral separation method in the mineral processing, which separates valuable minerals from the ore by means of the physicochemical properties of mineral surfaces...
