We report the electrochemical characterization of chitosan films deposited at gold electrodes from an acidic solution at reducing potentials. Cyclic voltammetry was used to characterize the deposition and electroactivity of chitosan coated gold electrodes. Chitosan films were found to deposit at gold electrodes at potentials more negative than −1.0 V versus Ag/AgCl, a potential associated with ...
The so-called ‘mesothermal’ gold deposits are associated with regionally metamorphosed terranes of all ages. Ores were formed during compressional to transpressional deformation processes at convergent plate margins in accretionary and collisional orogens. In both types of orogen, hydrated marine sedimentary and volcanic rocks have been added to continental margins during tens to some 100 milli...
Laboratory studies have been carried out on the processing of gold-bearing concentrate from “Jamgyr” deposit using JIN CHAN reagent. The influence concentration CHAN, duration leaching, temperature solution were studied. As a result research, extraction gold and silver into cyanide-free technology was 97,5% 96%, respectively. obtained solutions by method sorption MA940BG (gold) ion-exchange res...
