of(RO)2P(O)OPh-COOH as carrier, polyisocrotyl succinimide(T154) as surfactant, sulfonated kerosene as diluent, phosphoric acid(H3PO4) as stripping solution. Different chemical parameters such as type and concentration of carrier, surfactant, stripping solution, volume ratio of oil phase to internal phase, and volume ratio of emulsion ratio to external phase were analyzed. The extraction of RE3......

, good ductility and elasticity, the effect of solution treatment and aging on microstructure and mechanical properties was studied for TB12 (Ti-11Mo-5Zr-4Sn-3Nb, mass fraction, %) alloy newly developed for dental orthodontics. The results show that the increase in solution temperature leads to the growth of β grain, while no obvious influence on mechanical properties. The solution treated alloy......
Extraction and stripping of rare earths using mixtures of acidic phosphorus-based reagents王香兰1,李薇2,李德谦31. Department of Chemistry and Environmental Engineering,Wuhan Bioengineering Institute2. School...(Ⅲ),Yb(Ⅲ),Lu(Ⅲ) from the other rare earths. Taking Yb(Ⅲ) as an example,based on the different stripping acid,the potential of the stripping was estimated.关键词:......

for forged and solution treatment in different temperatures 图3 不同温度固溶处理的XRD谱 Fig. 3 XRD pattern of rods for solution treatment at different temperatures 图4所示为合金棒材固溶处理后的拉伸性能.经比较发现,当固溶温度较低时,固溶态的强度... properties of Ti-662 alloy rods of forged and as-solution treated 从图4显示的趋势来看,随着固溶温度的提高,强度逐渐升高的同时断面收缩率随之下降,而伸长率也略有下降的趋势.这是因为当固溶温度较低时,组织中的等轴α相数量较多,β相较少,β稳定性元素含量较高,所以水淬时β相转变为斜方马氏体α″相.当固溶温度提高时,组织中的等轴α相数量逐......

(2007)04-0584-05 DOI: 10.1007/s11771-007-0112-2 Experimental study on preferential solution flow during dump leaching of low-grade ores YIN Sheng-hua(尹升华)1, WU Ai... solution flow during dump leaching of low-grade ores was studied. The formative mechanism of preferential solution flow was investigated through analyzing the relationship between permeability and ore......

(CCS) study. The stripping of total rare earth from loaded organic phase(LO) was conducted using HCl solution. Mc-Cabe Thiele diagram study carried out at A:O=1:5 using 4 mol/L HCl showed that three theoretical stages were needed for quantitative stripping of total rare earth. The subsequent stripped solution resulted thus led to contain total rare earth of 5.6 g/L indicating a very high enrichment......
