J. Cent. South Univ. (2019) 26: 2328-2339 DOI: https://doi.org/10.1007/s11771-019-4177-5 Water leaching of arsenic trioxide from metallurgical dust with emphasis on its kinetics YANG Kang(杨康)1, LIU... enough arsenic in the leaching solution or in leaching out all the soluble arsenic with excess dosage of water within acceptable time (120 min). Only about 73% of As2O3 was extracted under the optimal......

Behavior of arsenic in zinc electrowinning YU Xiao-hua(俞小花)1, XIE Gang(谢 刚)1, LI Rong-xing(李荣兴)1, LI Yong-gang(李永刚)2, LU Ying(陆 莹)1 1. Faculty of Metallurgical and Energy Engineering, Kunming... ____________________________________________________________________________________________ Abstract: The effects of arsenic on the cathode polarization process in zinc electrowinning, its kinetics equation......
Valence variation of arsenic in bioleaching process of arsenic-bearing gold ore CUI Ri-cheng(崔日成), YANG Hong-ying(杨洪英), CHEN Sen(陈 森), ZHANG Shuo(张 硕), LI Ke-feng(李科峰) School of Materials... resistance for the As3+ and As5+ and converting conditions from As3+ to As5+ were analyzed. The additive was used to prompt the bacterial leaching efficiency by changing valence state of arsenic......
Relaxations and bonding mechanism of arsenic in-situ impurities in MCT: first-principles study Sun Li-zhong(孙立忠)1, 2, Zhong Xiang-li(钟向丽)1, Wang Jin-bin(王金斌)1, Chen Xiao-shuang(陈效双... Abstract: The structural and electronic properties of the arsenic in-situ impurity in Hg1-xCdxTe(MCT) were studied by combining the full-potential linear augmented plane wave (FP-LAPW) and plane-wave......

Effect of mixed moderately thermophilic adaptation on leachability and mechanism of high arsenic gold concentrate in an airlift bioreactorYU Run-lan(余润兰), WU Fa-deng(吴发登), CHEN An(陈安), SHI Li-juan(石丽... gold concentrate with 19% arsenic was treated by a mixed moderately thermophiles in an airlift bioreactor through an adaptation protocol. The moderately thermophiles could respond well to 20% (w/v......
VACUUM-THERMAL ARSENIC EXTRACTION FROM GOLD-CONTAINING SULPHIDE CONCENTRATESIsakova R.A.,Chelokhsaev L.S.,Khrapunov B.E.,Spivak M.M.,Fedulov I.O.摘 要:<正> Arsenic is often occured in sulphide gold-containing ores and concentrates. The principal minerals of these materials are arsenopyrite (FeAsS), auripigment (As2S3), realgar(As2S2) and lollingite......
