J. Cent. South Univ. Technol. (2008) 15: 808-813 DOI: 10.1007/s11771-008-0149-x Thermal decomposition behaviour of polyacrylamidomethyltrimethyl ammonium chloride in red mud separation process HU... for selecting highly efficient red mud flocculants, the behaviour of polyacryl- amidomethyltrimethyl ammonium chloride (PATAC) in red mud separation process was investigated. PATAC was employed......
J. Cent. South Univ. Technol. (2008) 15: 378-381 DOI: 10.1007/s11771-008-0071-2 Flotation of kaolinite and diaspore with hexadecyl dimethyl benzyl ammonium chloride HU Yue-hua(胡岳华), OUYANG Kui.... And then the synthesized tertiary amine was used to react with benzyl chloride to synthesize hexadecyl dimethyl benzyl ammonium chloride (1627) at ambient pressure. Using the synthesized 1627......
"><正>A new process of enriching germanium from coal ash was developed. The process involves in mixing the coalash and ammonium chloride and then roasting the mixture to produce germanium chloride...Recovering germanium from coal ash by chlorination with ammonium chlorideZHU Guocai, SHI Wenzhong, and TIAN Jun Institute of Nuclear Energy Technology, Tsinghua University, Beijing 102201, China......
Removal of vanadium from ammonium molybdate solution by ion exchange LI Qing-gang(李青刚)1, 2, ZHANG Qi-xiu(张启修)2, ZENG Li(曾 理)2, XIAO Lian-sheng(肖连生)1, 2, YANG Ya-nan(杨亚男)2 1. State Key Laboratory... kinds of chelate resins were used to investigate the adsorbent capability of V(Ⅴ) in ammonium molybdate solution with static method. The test results show that DDAS, CUW and CW-2 resins can easily......
Extraction of cobalt from laterite ores by citric acid in presence of ammonium bifluoride LI Guang-hui(李光辉),RAO Ming-jun(饶明军), LI Qian(李 骞), PENG Zhi-wei(彭志伟), JIANG Tao(姜 涛)1 School... in the presence of ammonium bifluoride. The results show that ammonium bifluoride enhances the leaching of cobalt by citric acid, and 84.5% cobalt is extracted from a laterite ore containing 0.13% Co......
that the collecting ability of quaternary ammonium salts for the four minerals is in the order(from strong to weak) of octadecyl dimethyl benzyl ammonium chloride(ODBA), cetyl trimethyl ammonium bromide(CTAB), dodecyl trimethyl ammonium chloride(DTAC). Under the condition of alkalescence, it is possible to separate the diaspore from the silicate minerals such as kaolinite, illite and pyrophyllite......
Dissolution kinetics of low grade complex copper ore in ammonia-ammonium chloride solution LIU Wei(刘 维), TANG Mo-tang(唐谟堂), TANG Chao-bo(唐朝波), HE Jing(何 静), YANG Sheng-hai(杨声海),YANG Jian-guang(杨建... complex copper ore was investigated in ammonia-ammonium chloride solution. The concentration of ammonia and ammonium chloride, the ore particle size, the solid-to-liquid ratio and the temperature......
, and the stirring time should be controlled within 1 h. The ammonium chloride concentration should be controlled within m(NH4Cl)?m(glycerin)=0.15. Key words: refined indium; chemical purifying process; glycerin; potassium iodide; ammonium chloride 半导体及薄膜太阳电池等材料对金属铟的纯度 要求很高......
