Recovery of vanadium from black shale LI Cun-xiong(李存兄), WEI Chang(魏 昶), DENG Zhi-gan(邓志敢), LI Min-ting(李旻廷), LI Xing-bin(李兴彬), FAN Gang(樊 刚) College of Metallurgical and Energy Engineering... ____________________________________________________________________________________________ Abstract: The recovery of vanadium from a black shale from Guizhou Province of China was performed using a three-step process, which consists of a leaching step in the H2SO4-HF-NaClO system......
Recovery of gallium from phosphorus industry flue XU Ke(许 可), DENG Tong(邓 彤), DAI Yu-jie(戴玉杰), WANG Jing(王 静) (Institute of Process Engineering, Chinese Academy of Sciences, Beijing 100080, China) Abstract: The flue dust generated during electric furnace production of elemental phosphorus was investigated for the recovery of gallium. Then the flue dust was slurried with water......
reflected by flow curve which is a direct consequence of microstructural changes involving work hardening (WH), dynamic recovery(DRV) and dynamic recrystallization(DRX). The calculation of the forces.... The constitutive equation of stress-strain curves was expressed in terms of dynamic recovery region and dynamic recrystallization region, in which the effect of dynamic recrystallization on flow......

for the continuous DRX occurring at elevated deformation temperatures in present work, yet is different from the dynamic recovery (DRV) proposed by McQUEEN [32] or the low-temperature DRX described in Ref. [3...Trans. Nonferrous Met. Soc. China 26(2016) 378-389 Dislocation mechanism for dynamic recrystallization in twin-roll casting Mg–5.51Zn–0.49Zr magnesium alloy during hot compression at different strain......
Sulfuric acid recovery from rare earth sulphate solutions by diffusion dialysis TANG Jian-jun(唐建军)1, ZHOU Kang-gen(周康根)2, ZHANG Qi-xiu(张启修)2 1.School of Construction...; accepted 22 December 2005 Abstract: Sulfuric acid recovery from rare earth sulphate solutions by diffusion dialysis was studied. The mass transfer model of diffusion dialysis was established, the comparison......
are mainly made of twinning. Under the general deformation condition, dynamic recovery mainly occurs in high stacking fault materials, However, dynamic recrystallization occurs at a lower temperature...;. With the combined forces including drawing, compressing and shearing, severe plastic deformation was obtained during the asymmetric rolling, promoting dynamic recrystallization at room temperature. Because......
