Re: Building a small silver recovery unit

Well as the one that started this I was far less concerned about whether
it was smart from an economic point of view. For the volumes I do I
know its not. The buckets are a pain. I don't have the resources to
spend the kind of cash it would take to buy the factory made ones. Those
run into the thousands and that investment would be far better spent on
a large format Epson 9600 inkjet printer than a recovery system.

So can someone kindly explain the "steel wool" method teasingly
described above? I asked about it but received no replies. Am I in
everyone's killfile here? or isn't it worthy of discussion?

I'm not quite sure what you want explained. A simple approach is, put
a blob of steel wool in a liter of used fixer, wait a few days and
throw the mess away.

So a guy could, say, pour off the excess liquid, let the remaining "mess" dry, then take it (the steel + silver) to a local hazardous materials drop-off site?

In case you want to keep the silver, filter the mess and discard the
liquid. What you have left is most of the silver and some residue
of iron from the steel wool. The iron can be disolved in acid.

Some folks don't like discarding disolved heavy metals down the drain.

I don't like it, no.
