Ore Minerals and Metal Distribution in Tailings of Sediment-Hosted Stratiform Copper Deposits from Poland and Kazakhstan

چکیده
This study, carried out in tailings from two sediment-hosted stratiform copper deposits the Lublin-Głogów Copper District Poland (Kupferschiefer-type deposit) and Zhezkazgan (cupriferous sandstone-type Kazakhstan, analysed mineralogy of copper, zinc, lead minerals as related to metal accumulation sediments. Microscopic study reflected light SEM–EDS (Scanning Electron Microscope—Energy Dispersive Spectrometer) analysis, well chemical diversity used INAA (Instrumental Neutron Activation Analysis), ICP (Inductively Coupled Plasma), AAS (Atomic Absorption Spectroscopy) methods 35 samples Kazakhstan were examined due their diversity. In both tailing Poland, heavy fractions dominated by sulphides: chalcopyrite (CuFeS2), bornite (Cu5FeS4). chalcocite (Cu2S). Moreover, sphalerite, galena, cerussite have been recognized a carriers Zn Pb. Their geochemistry was Cu, showing mean content 2500 ppm, Kazakhstan. Zinc also occurred, approximately 200 ppm 500 1500 Pb respectively. Grain size analysis indicated that dominant grain districts corresponded silt fine sands fractions. Copper, zinc sulphides accumulated (in sandstones quartz grains), mainly coarse (within carbonates, sandstones, black shales). Mineralogical geochemical features should be taken into consideration when assessing potential sources technogenic materials.

The Sorkheh deposit in northwestern Iran exhibits several readily visible general characteristics of sediment-hosted stratiform copper (SSC) mineralization. It consists of fine-grained disseminated base-metal sulfides within gray sandstones (gray beds, the basal whitish Miocene sandstone and shallow-water) that overlie a thick sequence of red beds (Miocene Upper Red Formation). The host gray be...

Early diagenetic sediment-hosted stratiform copper (eSSC) mineralization results from low-temperature cuprous chloride complexes carried by saline aqueous solution circulating through footwall aquifers. Favorable copper solubilities are attained in moderately oxidizing, near-neutral pH solutions. That specific oxidation level is not determined by co-existence with hematite, with its near-indisc...
