Effect of impurity ions on preparation of novel saponifier for rare earth extraction肖燕飞,冯宗玉,黄小卫,黄莉,徐旸,侯永可,王猛National Engineering Research Center for Rare Earth Materials,General Research Institute... as a novel saponifier to eliminate the ammonia nitrogen pollution in the rare earth extraction separation process.The effect of impurity ions introduced by system on the carbonation reaction of magnesium......
conditions. It is found that the environment-friendly depressant LG-01 can react with the impurity ions through the formation of a new complex on the surface of leaching residues. Thus, it reduces significantly the concentration of impurity ions in leaching solution and improves the leaching rate of rare-earth ore. Moreover, a leaching rate of 95.6% and an impurity removal rate of 92% have been......
kinetics studies of both rare earth ions and impurity ion Al3+ were conducted in the ammonia-nitrogen wastewater system with the aid of impurity inhibitors.Results showed that the leaching process of rare... control, but the hybrid control model which was affected by a number of process factors.Thus, during the industrial production the leaching of impurity ions could be reduced by increasing......

School of Minerals Processing... difference between sulfide minerals and quartz in sulfide ores flotation, SiO2 is still the main impurity in sulfide concentrate, therefore it is the main factor which influences the quality of sulfide......
Preparation and property of spinel LiMn2O4 material by co-doping anti-electricity ions XIAO Jin(肖 劲), ZHU Hua-li(朱华丽), CHEN Zhao-yong(陈召勇), PENG Zhong-dong(彭忠东), HU Guo-rong(胡国荣) School... fades. The results of cyclic voltammetry indicate that the shape of two couples of redox peaks of the material synthesized by co-doping anti-electricity ions is more integrate and symmetrical than......
