Hello.
In a aqua regia solution containing gold , platinum , palladium ...
What will be the best method to precipitate all one by one.
From my knowledge,
Bubbling so2 gas first to drop gold.
Then evaporation of the solution to reduce it's volume then add saturated ammonium chloride solution for platinum precipitation and again reduce volume with evaporation then diluting with saturated solution of dmg+water for palladium.
If anything wrong please correct..
And this will on apprx. 10 litters solution not on small scale for me .
