# Iron-platinum refining

If I have an iron-platinum alloy, can I put this into a solution of $\ce{HCl}$ to dissolve the iron, leaving a $\ce{Pt}$ precipitate?

I know that Fe dissolves in $\ce{HCl}$ to form $\ce{FeCl2}$ and $\ce{H2}$, and I know that $\ce{Pt}$ does not dissolve in $\ce{HCl}$.

But will the $\ce{Fe-Pt}$ bonding affect the Fe dissolution?

• Given the broad solubility ranges and ordered low temperature phases, the general answer is no - those are alloys, not phase separated. – Jon Custer Aug 15 '17 at 15:39
