Trans. Nonferrous Met. Soc. China 23(2013) 2383-2388 Characterization of apparent sulfur oxidation activity of thermophilic archaea in bioleaching of chalcopyrite Wei ZHU1,2, Jin-lan XIA1,2... of Education, Central South University, Changsha 410083, China Received 12 July 2012; accepted 30 October 2012 Abstract: The apparent sulfur oxidation activities of four pure thermophilic archaea, Acidianus......
a higher temperature and a lower pressure. The calculated suitable temperature range for sulfur recovery in this process is 392-490 K. The Mo content of molybdenum metal ball obtained by experiments is 93.69% and the S content of sulfur products reaches 98.6%. The impurity elements, such as P, S, Cu, As, Pb, Sn, in the molybdenum products are very low. Key words: molybdenum concentrate; vacuum......

Nitrogen and Sulfur Co-doped Porous Carbon Derived from ZIF-8 as Oxygen Reduction Reaction Catalyst for Microbial Fuel Cells韩午丽,颜学敏,JIANG Yu,PING Mei,DENG Xiaoqing,张研College of Chemistry and Environmental Engineering, Yangtze University摘 要:Nitrogen and sulfur co-doped porous nanocarbon (ZIF-C-N-S) catalyst was successfully synthesized derived from ZIF-8......
kinetics and the conversion rate. And sulfur can be successfully separated from the zinc sulfide concentrate as elemental sulfur. The reasonable experiment parameters are obtained as follows: the leaching... less than 44 μm. Under the optimum conditions, the leaching rate of the zinc can reach 95% and the reduction rate of the sulfur can reach 90%. Key words: zinc sulfide concentrate; pressure acid......
