# Thermal oxidation of gold(I) sulfide

As far as I know the chemistry of $\ce{Ag}$ and $\ce{Au}$ are almost the same; because $\ce{Ag}$ belongs to the 4d series and $\ce{Au}$ belongs to the 5d series, we know the size of 4d and 5d are similar, so their chemistry remains similar.

Thermal study and mechanism of $\ce{Ag2S}$ oxidation in air

In this paper, it is given that $\ce{Ag2S}$ can be oxidised thermally in the presence of $\ce{O2}$ to give $\ce{Ag}$ and $\ce{SO2}$ over 510 °C. I am not able to find any references where a similar experiment is done for $\ce{Au2S}$. Can somebody please help me ?

$$\ce{Au2S + O2 ->[200-500°C] 2Au + SO2}$$
