There is mercury on every speck of gold where I usually dredge. I usually burn it off with acid then precipitate the Hg back out for safe keeping. However, this process discolors the gold and using acid is always risky.
I have a full size retort but it's bulky so I decided to build something smaller that would process up to about 1 oz of amalgam.
