Electrochemistry reversing GP items

[colt45gto]

Along with the 9ct jewellery i have many GP items that will need to be recovered. i have heard a lower volt is best to help separate plated items than a higher 12v is this true?

I'm assuming you're talking about a sulfuric cell.

It's actually the current that is more important than the voltage, although the initial current will be proportional to the voltage, assuming it is unfettered.

I don't want to confuse you by going deep into electrical properties. But some members like to use a 12V supply with a light bulb (say, an auto brake [21W] or tail [5W] lamp) to reduce the current. This will, in effect, also reduce the voltage across the cell. And as the gold is deplated the current will taper off anyway as electrical resistance increases.

Keeping your solution cool is also quite important.
I hope this little bit helps. There are a gazillion posts about cells here. But if you have a further specific question, we will all try to help.
