I've been reading over many things lately and had some questions that I wasn't sure about. I didn't want to make a new thread for each of these questions, but a moderator can split them up if needed.
I have a large bag of slaked lime "Calcium Hydroxide" in the garage that I was going to use to neutralize my waste solutions when I get around to it.
I'll most likely use the HCl +Aluminum conversion in this thread for any AgCl. http://goldrefiningforum.com/phpBB3/viewtopic.php?f=50&t=732&hilit=hcl+aluminum+silver+chloride I get scrap Aluminum quite often.
My questions are...
If I use the HCl + Aluminum conversion, after the Aluminum is dissolved, can I drop it out as powder using Calcium Hydroxide to neutralize the solution? (The same way I would treat waste solutions) Afterwards, I could make some Aluminum bars, pound it into a sheet and re-use to convert more AgCl.
I was wondering if this would work also.
If I use HCl on silver mylars, since the silver is so thin, it should turn into AgCl right?
If so, can I use Calcium Hydroxide with Karo "or sugar", instead of Sodium Hydroxide and Karo to convert the AgCl back to silver?
Will the HCl dissolve the Mylar itself, or just remove the silver?
Edit - I thought this might work, because of this thread. http://goldrefiningforum.com/phpBB3/viewtopic.php?f=34&t=14623&p=230303&hilit=silver+keyboard+hcl#p230303 At the very end of it I noticed comment.
Another question,
Is it possible to remove the green mask from circuit boards using Calcium Hydroxide instead of Sodium Hydroxide?
If so, can I filter out the green mask afterwards and use the leftover Calcium Hydroxide for converting AgCl?

FrugalRefiner said:But this thread is about keyboard mylars, which are silver. AR of any type or HCl/bleach will not dissolve the silver. They will turn it into insoluble silver chloride.
