Platinum Refining slide show

[Gigidag]

Dear Lou,

We have a question concerning dropping down Platinum from aqua regia solution.

Unfortunately when we drop down with ammoniumchloride we still have around half of the amount of the platinum in the solution. What can we do?

Your help is highly appreciated.

kind regards

Does any one know the initial metal that was used?
