Thermodynamic calculations for the volatilization of arsenic and lead from molten copper at high oxygen level were performed using available thermodynamic data. An experimental setup was built in order to validate the predictions. Three experimental tests confirmed both the moderate volatility for Pb species (Pb+PbO) and the extremely low vapor pressure of As-O species, even at high oxygen and arsenic levels in molten copper.
