Trans. Nonferrous Met. Soc. China 26(2016) 1112-1117 Flotation of low-grade bauxite using organosilicon cationic collector and starch depressant Xin-yang YU1, Hao-lin WANG1, Qiang-qiang WANG1, Bo... and pyrophyllite, using an organosilicon cationic surfactant (TAS101) as collector and starch as depressant was investigated. The results show that both diaspore and aluminosilicate minerals float readily......

sites[25]. Thus, the coupled inner-surface hydroxyl sites may leave naked O anions alone, which offers a chance to hydrogen bond to cationic collector molecules. 3.3 Application... Comparative studies on flotation of illite, pyrophyllite and kaolinite with Gemini and conventional cationic surfactants XIA Liu-yin(夏柳荫)1,2, ZHONG Hong(钟 宏)2, LIU Guang-yi(刘广义)2, HUANG Zhi-qiang......
was collected from Guizhou Province, China, and the loss on ignition (LoI) is 16.90%. HAY is a kind of amine cationic collector for phosphate ore flotation. H2SO4, HCl and NaOH were purchased from...J. Cent. South Univ. (2017) 24: 30-38 DOI: 10.1007/s11771-017-3405-0 Adsorption of residual amine collector HAY from aqueous solution by refined carbon from coal fly ash and activated carbon LI Xian......
A new collector used for flotation of oxide minerals LIU Wen-gang(刘文刚)1, WEI De-zhou(魏德洲)1, WANG Ben-ying(王本英)2, FANG Ping(方 萍)1, WANG Xiao-hui(王晓慧)1, CUI Bao-yu(崔宝玉)1 1. School...: A surfactant containing a mixed aliphatic structure, with a hydrocarbon chain and a diamine group, has proven to be collector for the flotation of quartz, calamine and calcite. And research about......
surface; With smaller HOMO-LUMO GAP(△ε) than twelve amine cationic, GE cationic has higher reactivity and stronger collecting ability. Key words: cationic collector; jasper; magnetite; adsorption mechanism... as cationic collector for iron ore flotation[J]. Separation and Purification Technology, 2013, 103: 187-194. [3] Geraldo M B, Antonio E C P. Residual amine in iron ore flotation[J]. Minerals......
in the slurry of pH 9-10[3-7]. But the cationic collector reverse flotation has shown some promising advantages for diasporic-bauxite de-silication over direct floatation, such as lower cost, easy...; Abstract: The hydrophobic aggregation of ultrafine kaolinite in cationic surfactant suspension was investigated......
and pyrophyllite, by a cationic Gemini surfactant as collector and starch as depressant was investigated as function of reagents concentration and pulp pH. Further studies of artificially mixed minerals and bauxite ore were also detailedly conducted. At last, the pre-desliming reverse flotation separation process was adopted. It can be concluded that the combinational use of a Gemini cationic collector......
force microscopy (AFM). Adsorption morphology images and interaction forces of cationic surfactants at solid-solution interfaces were measured in tapping mode and PicoForce mode, respectively... also showed a significant impact of hydrocarbon chain length on adsorption. An adsorption simulation was established to give a clear understanding of the interaction between cationic surfactants......
