of DEOECTU with Zn2+, Pb2+, Fe3+ or Fe2+ is observed under the experimental conditions. The results of adsorption measurement demonstrate that DEOECTU can be chemically adsorbed on chalcopyrite surface, and the adsorption amount of DEOECTU on chalcopyrite surfaces is further greater than on pyrite, sphalerite or galena surfaces. The flotation results of pure minerals were further confirmed......
has been reviewed, with an emphasis on China. In future, further studies on bioleaching of chalcopyrite, rare metals, secondary resources from waste, and environmental pollution caused by resource......
paragenesis minerals(such as pyrite, chalcopyrite, sphalerite and galena) in combination with tellurium-bearing minerals(hessite, sylvanite and Tellurobismuthite) were studied. Indigenous microbes from......
Numerical simulation analysis of Guixi copper flash smelting furnaceLI Xinfeng, MEIChi, and XIAO Tianyuan National CIMS Engineering Research Center, Tsinghua University, Beijing 100084, China Department of Heat Engineering, Central South University, Changsha 410083, China摘 要:<正>A numerical simulation analysis for reactions of chalcopyrite......
sulfide as pyrite, arsenopyrite, chalcopyrite and marmatite after irradiation were examined by flotation in a modified Hallimond tube. Experimental results show that the hydrophobicity of crystalline......
/energy dispersive spectrometer) and LRM (laser Raman microprobe) analysis show that these daughter minerals in garnet are sylvite, halite, sphalerite, chalcopyrite and carbonate. Sylvite daughter......

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... brierleyi (JCM 8954), Metallosphaera sedula (YN 23), Acidianus manzaensis (YN 25) and Sulfolobus metallicus (YN 24) and their mixture in bioleaching chalcopyrite were compared, which were characterized......
on the formation of the Kaerqueka polymetallic deposit is always an interesting topic of research. We used the finite difference method to model the mineralizing process of the chalcopyrite in this region... with the chalcopyrite formation in the Kaerqueka polymetallic deposit. The numerical results indicate that the hydrothermal fluid flow is a key controlling factor of mineralization in this area......
was adopted to single out the galvanic and passivation effects with four sets of minerals: pyrite-silica, chalcopyrite-silica, sphalerite-silica and stibnite-silica. Pyrargyrite enhanced Au recovery to 77.3... galvanic and passivation effects from sphalerite. Pyrargyrite associated with chalcopyrite retarded gold recovery to 38.0% and 12.1% (vs 57% and 14.1%) under galvanic and passivation effects. Accumulative......
