Abstract In the present work, electrodeposition of Zn–Ni alloy from Sulfate bath was carried out in presence a novel brightener (CG), condensation product Cysteine Hydrochloride and Glutaraldehyde. The corrosion studies were using Electrochemical Impedance spectroscopy Potentiostatic techniques. They confirmed an increase resistance protection ability bright zinc–nickel coatings. Surface morpho...

The Pb-Zn-Cu deposit of Ulldemolins occurs within the Carboniferous sedimentary series of the southernmost Catalonian Coastal Ranges. It consists of sulphide-bearing calc-silicate assemblages, with epidote, Ca-amphiboles and Ca-garnet, which develop selectively along a dolomicrite bed near the contact with a granite porphyry. Two mineralisation styles can be differentiated: a) banded and b) irr...

HAL is a multi-disciplinary open access archive for the deposit and dissemination of scientific research documents, whether they are published or not. The documents may come from teaching and research institutions in France or abroad, or from public or private research centers.

Principal Skarn deposits along the northern margin of the Ahar batholith from west to east include Mazraeh, Vine and Gowdoul skarn deposits. Among these skarn deposits, the Mazraeh Cu-Fe Skarn deposit is the most typical skarn deposit in the NW Iran. This skarn deposit is located 5 km. north of Mazraeh village and 20 km north of Ahar town. The origin and development of the skarn can be related ...

Abstract Laser ablation-inductively coupled plasma-mass spectrometry and electron-probe microanalysis were used to investigate the trace-element contents of sphalerite, chalcopyrite pyrite from Plaka Pb–Zn–Ag deposit. Using petrographic observations, analytical results could be linked temporal evolution ore-forming system. Sphalerite chemistry reliably records temperature f S 2 system, with est...

The Fule deposit is a typical Cd-, Ge- and Ga-enriched Pb-Zn located in the southeast of Sichuan–Yunnan–Guizhou polymetallic ore province China. Zoned, euhedral cubic pentagonal dodecahedral anhedral pyrites were observed, they are thought to comprise two generations. First generation pyrite (Py1) homogeneous entirely confined crystal core, whereas second (Py2) forms bright irregular rims aroun...

Abstract Zinc ion dissolved in water is attempted to be removed by generating the oxides of zinc using oxygen gas dielectric barrier discharge (DBD) plasma system. The removal rate oxides’ production (ZnO and Zn(OH) 2 ) are measured at different treatment periods penetration water. deposit increases initially then decreases with period. maximum (29%) from achieved period 10 min, where pH lower ...
