), which generally act as depressant and collector, respectively, in the reverse flotation of bauxite, was investigated using starch-iodine tests. The results obtained from the blue-value measurements...; dodecylamine; reverse flotation 1 Introduction Over decades, starch has been practically used as depressant and flocculant in the minerals processing industry for froth flotation [1......
Flotation techniques for separation of diaspore from bauxite using Gemini collector and starch depressant XIA Liu-yin(夏柳荫), ZHONG Hong(钟 宏), LIU Guang-yi(刘广义) School of Chemistry and Chemical... 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......
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......

of electronic structure on the adsorption of depressant were investigated. And the competitive adsorptions of starch fragment, water and hydroxyl ions on (001) surface of hematite were discussed...; reverse-flotation; depressant; starch Foundation item: Project(51304022) supported by the National Natural Science Foundation of China; Project (2013AA064102) supported by the National High Research......
Article ID: 1003-6326(2005)02-0257-04 Preparation of porous hydroxyapatite ceramics with starch additives YANG Lei(杨 磊), NING Xiao-shan(宁晓山), CHEN Ke-xin(陈克新), XIAO Qun-fang(肖群芳), ZHOU He... prepared from nano-sized hydroxyapatite powders by adding water soluble starch and insoluble starch were investigated. The results show that small pores of several micrometers or less can be produced......
amounts of DDA adsorption at 100 mg/L starch concentration at pH=9 (Fig. 5), the latter indeed performs a much better depressant in micro-flotation (Fig. 1). One reason for this is that, as already.... Dextrin as a non-toxic depressant for pyrite in flotation with xanthates as collector [J]. Minerals Engineering, 2004, 17(9-10): 1001-1006.
