[QUOTE="user 4386, post: 632286, member: 4386"] I am not aware of cyanide use being usual in puddlers - puddlers were designed to mechanically get sticky clay into suspension in water so as to free up contained gold. Also cyanide is a carbon and nitrogen compound that rapidly decomposes in contact with oxygen in the atmosphere (certainly all gone within decades if not years).The only place where some toxicity might remain after all this time is in crushed quartz from mineralized veins (quartz sand tailins), where the cyanide has reacted with metals to leave metal cyanide residues (the original cyanide will have gone). But not a likely source of harm even then, but I would not have my kids use it as a sandpit. Yes, please leave puddlers and other mining relics alone. Just photos. [/QUOTE]
