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... from coal fly ash (CFA) as well as powdered activated carbon (PAC) was investigated as adsorbent to remove residual amine collector HAY from aqueous solution. The RC and PAC were characterized......
its collecting capability was carried out in laboratory. The test results show that the flotation recovery ascends sharply with increasing the concentration of collector. When the concentration... with the increase of collector concentration and pH, while the maximal recovery is not more than 55%. Compared with dodecylamine, the N-dodecylethylenediamine has strong capability to quartz and calamine, while......
generally designated as O-Si-O bending vibration, whereas 1081.32 cm–1 was the stretching vibration absorption peak of Si-O. Under the conditions of pH=11 and concentration of collector W-2 of 583.33 mg/t...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......
recovery increases, YOA-15 is the most efficient collector compared with sodium oleate and all of other collectors. Fe3+ activates sufficiently spodumene and beryl at a low concentration and at neutral pH values. Ca2+ can activate the minerals sufficiently only at a high enough concentration and at very high pH values. Key words: spodumene; beryl; flotation; collector 锂辉石和绿柱石是提取稀有金属元素锂......
