- Abstract
This study suggests the possibility and efficiency of application solutions treated under the contact non-equilibrium low-temperature plasma for intensification dissolution of silver in cyanide leaching systems. The obtained research results show that plasma activated solutions due to the complex of peroxide and super peroxides compounds, radicals and particles formed in water during processing have higher oxidizing properties compared to synthetic hydrogen peroxide and oxygen commonly used in the hydrometallurgical industry as oxidizing component. We investigate that the influence of main technology parameters on the speed of the process of silver dissolution in activated solutions, as well as synthetic hydrogen peroxide and oxygen. In addition, we show that the silver dissolution in all cases is characterized by transitional type kinetics proved by the calculated values of activation energies. The comparison of values of activation energies show the advantage of using activated solutions before adding synthetically hydrogen peroxide and oxygen.
