and X-ray diffraction shows that it contains essentially copper, lead, zinc and iron in the form of chalcopyrite, sphalerite and galena. A small amount of pyrite is also present in the ore but does... spectrometry and X-ray diffraction allow to conclude that the rate of dissolution of the minerals contained in the complex sulphide concentrate are in the order of galena>sphalerite>chalcopyrite. Key......
% and 97.29% under the optimal conditions, respectively, and the artificial galena, sphalerite and wurtzite were formed. By the novel sulfidizing process, it is expected that the sulphides can......
, arsenopyrite, sphalerite, galena and chalcopyrite are disseminated in the ore. Quartz, sericite and dolomite are the main gangue. The optimal grinding fineness should be chosen as 0.037 mm to make sure... are the main forms of tin mineral while the content order of metal sulfides is pyrrhotite > pyrite > arsenopyrite > sphalerite > galena > chalcopyrite. There is also bismuthinite......

of sphalerite and a few of marmatite. 54.78% Sn exists as cassiterite monomers, and 41.31% Sn is embedded in magnetite, existing as the form of tiny granule inclusion of cassiterite, which is proved by the results of Electron Probe. 88.95% Zn exists as sulfide minerals, in addition, granular and irregular sphalerite particles are enwrapped in the magnetite and other minerals. 2 380 N/P of pellet compression......
followed by galena and sphalerite, the mass fraction of pyrite is 46.30%, and most size of the three minerals is under 0.03 mm. The monomer dissociation degrees of pyrite, galena and sphalerite... sulfide (reflection) (Gn: Galena; Sp: sphalerite; Py: Pyrite; G: Gangue) 镜下分析结果照片分别显示,形态规则的单体粒状方铅矿(Gn),黄白色微粒为黄铁矿反光(见图1(a)), 闪锌矿(Sp)与方铅矿(中部白色)连生体,黄白色微粒为黄铁矿反光(见图1(b)),单体粒状闪锌矿(Sp),黄白色微粒为黄铁矿,脉石(G)反光(见图1(c......

analysis reveals that the structure of ZnSe phase is sphalerite (cubic ZnS). The XPS results show that the atomic ratio of Se to Zn is 1?1 approximately. The TEM shows that the size of ZnSe... is shown in Fig.4. The XRD pattern indicates that the phase structure of ZnSe is sphalerite (cubic ZnS) without the appearance of ZnO phase. Fig.4 XRD pattern of ZnSe using ZnSeO4·H2O crystallites......
of zinc is sphalerite, of lead is galena, and that of copper and cadmium is sulfide, respectively. But, the mineralogical components of silver and indium in slag are opaque and probably stud in the crystal lattice of sphalerite with isomorphism. The speciation of zinc, cadmium, copper, and lead in the slag exists mainly in residual forms. The percentage of acidic extractable forms of metals in slag......
