Amalgamation: Using Mercury to capture fine gold, retort ...

Interested in using mercury to recover gold and silver and get all the gold out of your black sands? There is often some very small sized gold in our concentrates, and it can be a lot of work to get all the gold out. Yet we make a lot of effort to capture the gold and we don't want to throw any fine gold away as it can be so valuable.
