Hi again grf. Quick question. I spent some time this morning reading thru the forum and studying up on stannic acid.. One thing I read was that it is insoluble in hcl.. And again, elsewhere it was mentioned that it is insoluble In AR. If this is the case, wouldn't it be pretty simple just to whip up some AR and go ahead and dissolve the gold that is mixed in with the tin paste? It seems I should be able to filter the AuCl while the paste stays behind.. Am I missing something?
