Hello friends , I have aproblem with precipitating pt and pd from an aqua regia solution that I made from an ore near by ,
It is giving a colored indication of stannus chloride test so I didn't found any precipitation of au with sadium metabisupfite , so I tested with pt and pd precipitation . I did adding aluminium foil . So I ve got a brownish color powder precipitation ,
Can any one please guide me on this situation .
Thank you and good day
I will update with the results coming week..thanks 😊
This is for test purposes for only , needs to know what are the metals consists of , only able to seperate mica right now,
Noop, I bathe the ore with 35 % hcl one day and washed.. and then with hno3 . And finally aqua regia .
Seems like Iron...
But it is hard to say.
Have you assayed your ore? Is it really cost effective to leach with AR?
I would suggest comparing SnCl2 test vs. low Palladium content standard.
