I've got a Pt coin and I want to do a practice refining, and I want to shoot a video of it.
This'll be my first time doing Pt.
I've already rolled it thin 0.24mm and cut into strips and twisted as per Hoke.
I'll start be incinerating to burn off any oils.
I plan to dissolve in hot AR, then denoxx via evaporation and hydration with HCl.
Then precipitate the Pt salt with ammonium chloride and calcine.
Any insight would be greatly appreciated.
Should I set up a reflux condenser, or just cover with a watch glass?
I'll be doing a 1/4 oz coin. Is there a certain concentration or pH I should attain before precipitating?
Is ammonium chloride the right precipitant, or should I go with something else?
Thank you!
