hello everyone i hope you all have a good day. i got into a big mess here, i scraped hundreds of cell phones, remove as much plastic as possible and also removed iron from it but still there is a big quantity of base metals, i burned everything for the acid to do a good job and i ended up with a half 5 gallon bucket full of copper mixed with all kind of metals from cell phones and computers in total is about 5 kilos of mixed boards

tried to separate every component manually because there is a considerable amount of palladium since most of the boards are from phones, ipads and computers but i found out is very difficult

there are all kind of mixed metals so i just added concentrated nitric acid to get first the copper, im new in this so i wonder if adding the acid was the right thing to do, there are many ics that neeed to be crush i think i made a mistake, please help

by the way i wanted to create a new post but it will not let me do it

same to you my halp

Okay

Re-dissolve with water/dilute HCl and add the copper

So what could I do if the precipitate has the pd?

Ok I already did that and I will let it for some days. But what if the precipitate do contain pd in it and there is no in the solution? Should I do tue SMB process?

Yes and what do yoy advice me to do?

Hi I made a 20ml DMG solution with 2grams DMG with 20ml water and I added like 15ml to the solution. Here is the precipitate I got. One friend told me to dissolve this precipitate in nitric acid and then dilute the solution and add SMB and a yellow palladuim precipitate will settpe but I am not sute should I do that?

Hi,

It sounds like you may have precipitated some hydoxides / oxides.

How much. DMG solution have you added? Is the leach solution still acidic?
