Trans. Nonferrous Met. Soc. China 23(2013) 796-803 Theory analysis and vestigial information of surface relaxation of natural chalcopyrite mineral crystal Shu-ming WEN, Jiu-shuai DENG, Yong-jun XIAN... was used to measure the unit cell parameters of chalcopyrite crystal. The results showed that the chalcopyrite crystal is perfect, and the arrangement of its atoms is regular. A qualitative analysis......
; 文献标志码:A Dissolution characteristics of apatite in chalcopyrite bioleaching system and its influence on chalcopyrite leaching efficiency ZHOU Shan-shan1, 2, LIN Hai1, 2, DONG Ying-bo1, 2, XU... and Environmental Engineering,University of Science and Technology Beijing, Beijing 100083, China) Abstract: To make sure the dissolution characteristics of apatite in the chalcopyrite bioleaching system......
minerals associated with calcite and dolomite, followed by quartz, remain the major minerals in both the ROM and tails streams. In the ROM stream, chalcopyrite appears to occur as veins within.... This metamorphosis was likely promoted by the concentration process. The concentration process was effective, upgrading the chalcopyrite content from 2 wt% in the ROM stream to 58 wt% in the concentrate stream......
Trans. Nonferrous Met. Soc. China 25(2015) 303-313 Comparison of electrochemical dissolution of chalcopyrite and bornite in acid culture medium Hong-bo ZHAO1,2, Ming-hao HU1,2, Yi-ni LI1,2, Shan... of Ministry of Education, Central South University, Changsha 410083, China Received 21 February 2014; accepted 16 July 2014 Abstract: The electrochemical dissolution process of chalcopyrite and bornite......

; 文献标志码:A Behaviour of Fe(Ⅱ) and Fe(Ⅲ) in chalcopyrite bioleaching process MA Peng-cheng, YANG Hong-ying, TONG Lin-lin, HAN Zhan-qi, SONG Yan (School of Materials Science and Metallurgy, Northeastern University, Shenyang 110819, China) Abstract: The chalcopyrite was bioleached using ferrous and ferric solution. The variations of main experimental......
Trans. Nonferrous Met. Soc. China 23(2013) 3063-3067 Selective depression of galena and chalcopyrite by O,O-bis(2,3-dihydroxypropyl) dithiophosphate Zheng-jie PIAO1, De-zhou WEI1, Zhi-lin LIU1,2, Wen...), was investigated as depressant on the depression of chalcopyrite and galena, when ammonium dibutyl dithiophosphate (DDTP) was used as the collector in flotation tests. Zeta potential and adsorption......
; Abstract: The adhesion of ferrous ions grown Leptospirillum ferrooxidans cells on pyrite and chalcopyrite... signifying cells adsorption. The bacterial cells adsorption on chalcopyrite was higher compared with pyrite, which agreed with cells greater depression effect on chalcopyrite flotation and pronounced......

of PGA has strong depression effect on chalcopyrite. Mo grade of 26.17% and recovery of 89.83% were achieved with rougher and scavenger one time and cleaners twice, while the recovery of Mo was deceased... on chalcopyrite surface much stronger than on molybdenite surface. FTIR results indicate a chemical absorption process for PGA on chalcopyrite surface and a physical adsorption process on molybdenite......
