A process for precipitating particles of platinum group metals KU Leuven
The present invention relates to a process for recovering platinum group metals from a feed containing one or more precursor compounds of one or more platinum group metal ions, wherein the process comprises the steps of(i) supplying to a cathode compartment of an electrochemical cell equipped with a cathode comprising a gas diffusion electrode with a porous electrochemically active material, the feed containing the one or more precursor compounds to form a liquid phase in the cathode compartment,(ii) supplying a CO2 containing gas to the cathode compartment,(iii) applying a potential to the ...
