dust in NaOH solution[J]. Journal of Central South University (Science and Technology) , 2014, 45(5): 1390-1396. [14] GUO Xue-yi, YI Yu, SHI Jing, TIAN Qing-hua. Leaching behavior of metals from high...多金属浸出率的影响 Fig. 4 Effect of HCl concentration on metals leaching rate 由图4可知,砷,锑,铅,锌的浸出率均随盐酸浓度的增加而增加.当盐酸浓度由3.0 mol/L增加到6.0 mol/L时,砷浸出率由96.64%增加到98.73%,浸出渣中砷品位由1.45%降低到0.93%；而在盐酸浓度为4 mol/L时浸出渣率为......

purpose of this analysis was to classify waste as to its ultimate hazard and to predict the long-term behavior of contaminants. Leaching toxicity of Zn, Cd and Pb in the sludge was all higher than... one. The leaching behavior of Pb was different from those of Zn, Cd and Cu in the residue (Fig. 5(d)). The concentration of Pb was low at the beginning, but increased with the extending of time......
Leaching of low grade zinc oxide ores in Ida2--H2O system DOU Ai-chun, YANG Tian-zu, YANG Ji-xing, WU Jiang-hua, WANG An School of Metallurgical Science and Engineering, Central South University.... The effects of leaching time, liquid-solid ratio (L/S), total concentration of Ida2- ([Ida2-]T), leaching temperature and pH on Zn leaching recovery and the dissolution of impurities such as Ca, Mg, Cu, Ni, Fe......

Trans. Nonferrous Met. Soc. China 23(2013) 3780-3787 Atmospheric oxygen-rich direct leaching behavior of zinc sulphide concentrate Zhi-feng XU1, Qing-zheng JIANG1, Cheng-yan WANG2 1. School... October 2012; accepted 14 October 2013 Abstract: The leaching behavior of main metallic sulphides in zinc concentrate under atmospheric oxygen-rich direct leaching conditions was studied through......
Leaching vanadium by high concentration sulfuric acid from stone coal CHEN Xiang-yang(陈向阳)1, 2, LAN Xin-zhe(兰新哲)1, 2, ZHANG Qiu-li(张秋利)1, MA Hong-zhou(马红周)1, ZHOU Jun(周 军)1 1. School... from stone coals by high concentration sulfuric acid was researched. The effect of the concentration of sulfuric acid, leaching temperature, leaching time and helper leaching agent on the extraction......
fly ash respectively have the optimal physical, mechanical and chemical characteristics. Glass-ceramics samples, produced from incinerator fly ash with desirable properties and the low leaching... behavior 1 Introduction Incineration has become an important treating method for municipal solid waste (MSW) due to the increasing difficulty to get suitable sites for landfill in China. However......
