Ok, now the question is if I electrostrip a gold plated on base
metal item, does it only remove the gold plate?
No. It will probably attack the base metal once it gets through the
also, where does the gold that was stripped go- if it remains
in the solution, can it be used to replate something else?
Some remaiins in solution, some gets deposited on the anode.
Remember that base metals are also taking into solution, and that the
stripping solution is not optimized for elextroplating. So attempts,
after the stripping solution is well saturated with gold, to reverse
polarity and redeposit the gold as a goold electroplate won’t work
well. The solution is not designed as a plating bath, and won’te
function well in that rile. You CAN plate out the gold if what
you’re trying to do is reclaim it for refining or the like.
