Hello members,
I have a 5gal bucket of waste solution that was only used to pour left over/exhausted diluted nitric acid from refining keyboard mylars. The recovery process has not been a problem, nor is there a problem with the waste solution that I have, but I want to make sure I'm doing everything correct and at the same time collect any, if there is any, remaining silver from it.
1) After adding silver from mylars to the diluted nitric I let it cook on low heat. After all the silver have been dissolved, I filtered the solution and put it in a beaker to drop the silver with copper.
2) After all the silver have been dropped, I then filtered the solution and put the waste into a 5gal bucket. I even put the waste filers in there too.
3) After letting the bucket get almost full, I would notice that if I took a plastic rod (from old vertical blinds) the solution would create a white cloud, almost looking like milk. But, if I let the solution settle for a day or so and then decant from the top and let the solution go into a beaker and stick a piece of copper in it, and then leave it there for a few days, nothing happens. No solution gets darker and no silver drops from the copper at all.
Here is the question(s) I have and hopefully someone can advise me on what I should be doing if I'm doing something wrong.
4) I plan to take out all the filters and pieces of plastic with plastic tongs and put them in a plastic bowl or similar to rinse them off. Then...
5) I plan to let the solution settle all the carbon and white cloud to the bottom of the buck for at least 2 days. Then...
6) I plan to filter the solution and capture the carbon and any other solids that won't go through the filter. Then...
7) I plan to let the solution settle for a day or so, and then "decant" the solution and once I've decanted everything, pour the remaining white cloud/mud into a glass beaker.
From there I am thinking about adding more water, letting the cloud settle, and then decanting the solution until it's all clear and then from there, let it dry out and melt... or...
After performing no# 7, add some dilute nitric to the solution and add copper to drop out the silver.
Any suggestions or recommendations are welcome. Pictures are posted. The solution is not contaminated with other chemicals or metals, except copper, which I'll drop the copper out of it with some steel once I get all the silver, and then neutralize the solution.
Thanks for your input!
[EDIT] I don't have any question marks on my post, so I actually didn't ask any questions... sorry... but your input is still appreciated!
