ABSTRACT
The results of pyrometallurgical refining of platinum-rhodium alloys from contaminants during induction remelting under the influence of oxygen are presented. The results of atomic emission, atomic absorption and X-ray fluorescence analyses are presented. The kinetic features of the reactions between the components in the purification process are considered. The effect of the dispersion of the refining powder on the rate of reactions is investigated.
