J. Cent. South Univ. (2017) 24: 2799-2804 DOI: https://doi.org/10.1007/s11771-017-3694-3 Copper smelter slag treatment by ammonia solution:Leaching process optimization R. Nadirov1, L. Syzdykova2...-Farabi Kazakh National University,Almaty, 050040, Kazakhstan Central South University Press and Springer-Verlag GmbH Germany,part of Springer Nature 2017 Abstract: The feasibility of copper smelter......
is of great significance in electrochemical sensing applications. A facile hydrothermal process for synthesizing copper vanadate nanocrystals with various morphologies (e.g., nanoparticles, nanobelts... of Cu3V2O7(OH)2·2H2O nanoparticles are greatly affected by the sources of copper salts. Figures 2(a) and (b) show the SEM images of sample S14 derived from Cu(CH3COO)2·H2O, and this product is mainly......
Trans. Nonferrous Met. Soc. China 22(2012) s820-s824 Microstructure of fast tool servo machining on copper alloy Hong LU1, Soo-chang CHOI2, Sang-min LEE1, Deug-woo LEE3 1. Department of Nano Fusion... performance of a piezoelectric-assisted FTS on copper alloy was evaluated. The results indicate that the quality of the microstructure depends mainly on two important factors: the cutting speed......
Purification mechanism of copper electrolyte by As(Ⅲ) XIAO Fa-xin(肖发新)1, 2, ZHENG Ya-jie(郑雅杰)1, WANG Yong(王 勇)1, JIAN Hong-sheng(简洪生)1, HUANG Xing-guan(黄兴远)2, MA Yu-tian(马玉天)1 1. School...)-O-Sb(OH)3)3]-O-Sb(OH)2·xH2O. The structure analysis shows that the copper electrolyte can be purified by As(Ⅲ) because the antimony arsantimonate precipitate forms. Key words: arsenic; purification......
