<p>[QUOTE=&quot;Conder101, post: 1561509, member: 66&quot;]&quot;High&quot; is a relative term.&nbsp; A gold bar refined from other sources might have say 1 part per billion of mercury in it while a bar refined from gold amalgum that was once 50% mercury&nbsp; might end up with 10 parts per billion of mercury in it.&nbsp; In both cases you still have gold that is better than .9999 fine gold, but one has ten times as much mercury in it.&nbsp; Melting it down will drive off the mercury but getting it all out is another matter.&nbsp; Also the gold/mercury mix will melt at a much lower temperature than the pure gold does.&nbsp; This is why &quot;pure&quot; metals are never really pure.&nbsp; it is very difficult to get every last little trace of everything out.&nbsp; In the case the gold from the Swiss vaults has a little more mercury in it than is normally seen so it is safe to assume that the source of the gold had more mercury in it.</p><p><br /></p><p><br /></p><p>Are you sure you&#039;re a lawyer?&nbsp; <img src="styles/default/xenforo/clear.png" class="mceSmilieSprite mceSmilie1" alt=":)" unselectable="on" unselectable="on" /></p><p>Oh to accomplish that task,&nbsp; I see.</p><p><br /></p><p>Heat the amalgam in a closed container that has a small amount of air forced in to maintain a positive pressure.&nbsp; Vent the container with a flue pipe that runs downward a little ways before turning to rise back upward.&nbsp; Put a cooling waterjacket around the rising flue pipe.&nbsp; As water flows through the jacket it cools the gases in the flue pipe condensing the mercury which runs back down the pipe to collect at the&nbsp; bend when the pipe starts going up.&nbsp; The liquid mercury can be tapped off the bottom of the flue pipe here and reused.&nbsp; The blower in the enclosed container ensures the boiled off mercury fumes travel down the flue pipe.&nbsp; You can probably recover better than 98% of your mercury this way.&nbsp; Any still remaining in the container that recombines with the gold as it cool will be in the top surface of the gold bar, lump whatever.&nbsp; Shave off this top surface and add it to the next batch of amalgam.&nbsp; Now you are recovering better than 99% of the mercury from the amalgam and most of what is left can be removed from the gold by other refining techniques.</p><p><br /></p><p><br /></p><p>Which is exactly how the old time miners used to do it, only they didn&#039;t have a propane burner.[/QUOTE]</p><p><br /></p>
