摘要：The main purpose of this study was to ascertain whether SnO was volatilized or not when SnO2 was reduced in diverse CO–CO2 mixed gases at temperatures above 975 °C. The results indicated that tin was inevitably volatilized as gaseous SnO(g) during the reduction process of SnO2 roasted at 975 °C–1100 °C under different CO–CO2 atmospheres. Roasting temperature and CO content in the CO–CO2 mixed gases obviously affected the tin volatilized fraction. The tin volatilized fraction always increased with the roasting temperature increasing, while it first increased sharply to a maximum value and then
