J. Cent. South Univ. (2017) 24: 178-189 DOI: 10.1007/s11771-017-3419-7 Nonlinear finite-element-based structural system failure probability analysis methodology for gravity dams considering... of concrete gravity dams. Traditional methods for estimating the failure probabilities are based on defined mathematical descriptions, namely, limit state functions of failure modes. Several problems......
University, Istanbul 34469, Turkey摘 要:Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes... and environmentally friendly operations. In this study, gold pre-concentrates were produced by the stepwise gravity separation and flotation techniques. The Knelson concentrator and conventional......
Continuous electromagnetic separation of inclusion from aluminum melt using alternating current ZHANG Bang-wen(张邦文)1, REN Zhong-ming(任忠鸣)2, WU Jia-xiong(吴加雄)2 (1. State Key... was put forward based on the utilization of a square separation pipe and a 50 Hz alternating current to produce electromagnetic force. It is experimentally found that with electrical current of 400 A/cm2......

silver-manganese ore with a grade of 3.15×10-4 was concentrated by a combined beneficiation technique including magnetic separation, flotation, reducing leaching and gravity desliming. The major silver... Separation of silver from silver-manganese ore with cellulose as reductant ZHANG Xiao-yun(张小云), TIAN Xue-da(田学达), ZHANG Dong-fang(张东方) College of Chemical Engineering, Xiangtan University......
Influence of earth gravity on reaction engineering of tubular reactor for high concentration tungsten ion-exchange ZHAO Zhong-wei(赵中伟), XIAO Lu-ping(肖露萍), GUO Chi-hao(郭持皓), CHEN Xing-yu(陈星宇... 2010 Abstract: The influence of gravity on the reaction engineering of tubular reactor is studied by analyzing the residence time distribution curves. The results show that upflow-feeding mode is more......
