precursors were investigated. And the influence of pulse parameters on film quality was studied. The chalcopyrite phase CuInSe2 films with smooth surface and stoichiometric composition are obtained.... Furthermore, the crystallinity is improved by annealing, showing the sharp and intense diffraction peaks of the (112), (220, 204) and (312, 116). The chalcopyrite structure is also confirmed......
a single-phase chalcopyrite structure with (112) preferred orientation. The surface morphology of CIS films is uniform and compacted. The absorption coefficient is larger than 104 cm-1... chalcopyrite structure is confirmed by the presence of the characteristic peaks of chalcopyrite (103) [5]. The peaks at 27.3?, 29.2?, 37.5?, and 46.6?, corresponding to (112), (103), (211), and (204......

F... 2019 Abstract: This paper elaborated on the sustainability of the copper extraction process. In fact, an alternative copper extraction route from mixed sulphide ores, chalcopyrite and chalcocite using......
and A. sendaiensis ATCC 27009T, YNTC-1 may be proposed to be a novel subspecies of A. sendaiensis. However, this viewpoint has to be confirmed by further studies. Co-bioleaching of pyrite and chalcopyrite... spring with the ferrous iron and sulfur oxidizing acidothermophile, strain YN22 of Sulfobacillus thermosulfidooxidans, and experiments for co- bioleaching of pyrite and chalcopyrite by mixing the two......

, the growth of A. ferrooxidans and its metabolism on the insoluble substrate S0 and CuFeS2 were promoted. After 24 d of bioleaching, the copper extraction yield of chalcopyrite at 10-2 g/L Tween-80... more fatty acids, which assure the contact between hydrophobic S0 and SOB [9-11]. GOVENDER and GERICKE [12] suggested that the flotation of chalcopyrite (CuFeS2) could be significantly increased......
