Abstract

The results of the thermodynamic evaluation of oxidative plasma copper refining efficiency recycled from impurities present in the feedstock are shown. It was established that the type of impurity factor increasing the efficiency of the plasma refining the potential change of Gibbs varies from 1,4 to 4, 8, and for silver, and of gold there is a transition from an unlikely to real positive state.
