- How to remove mercury from gold. I tried to vaporize the mercury in the potato but it didn't work. I may not have gotten the fire hot enough. I know you can burn the mercury off with a tourch but I was hoping to save it and re-use it to catch micro gold in my black sands. I then tried to use acid, which did remove some of the mercury from the gold. Though after draining the acid off and adding more water and baking soda, I couldn't recover the mercury.
Alot of us got started with you years ago. You are still on my favorites list. Looking forward to any old clip you can toggle together!
I really miss your content. Hope you are well. Your vids live on and have energized thousands of us!
Thanks Jim. I really appreciate that. I am glad you enjoy my video's. I have quite a few that I need to upload.
@@YankeeGoldProspect Gold can kill you if you touch it, just to let you know. It will penetrate rubber gloves too.
Great take , good idea with potato , i have to try it :) thanks
Great Gold, thx for sharing.

Id like to see the potato trick on the color never heard of that one, Good video thanks Tom
Mercury has an "affinity" for gold so to speak, those chunky silvery pieces are chunks of amalgam. I forged my own Vermont gold ring a couple of weekends ago and had to deal with a few silvery amalgamated nuggets. Wrapping everything in a swatch of heavy cotton fabric helps the flour and flakes together and becomes charcoal in the heat. I mix the gold with dry borax 20 mule team ( equal parts gold /borax). Outside in a breeze (important), put the little pouch in a divot on a fire brick and hit it with a propane or hotter torch. Holding the torch still to allows the heat to accumulate, you may need to turn the torch up high. Keep the flame oxidizing and organized. The gold should bead up in a couple of minutes, it might not be pretty. The bead can be brightened by reheating it and sprinkling "sal amoniac" powder generously over it while glowing.
Mercury has a very high vapor pressure so it evaporates completely, quickly and easily long before the liquid phase temperature of gold. Mercury is expensive so old timers used the potato, which has a high thermal density due to it's water content, to recapture some of the mercury. Because seldom if ever more than a few milligrams would be recovered by a gold panner, I consider recovery unnessary and less safe than a good burn off.
A safe and simple retort can be made by welding a rod with a little cup on the end verticly to a plate. A tube with a cap on the end is placed over the crucible/cup. The cap should rest at the hight of the cup, and the bottom of the tube should rest on the plate. Gold amalgam is placed in the cup and the whole assembly is placed in a tray of water. The cap is heated with a torch. This design does not allow presure to accumulate, you can find diagrams in image searches. It's the simplest retort ever.
You are awesome Yankee, I hope I get out your way some time.
Hey Jim! This is Eddie. Wanted to see how you are? Lost your number. I dropped my phone in a creek and no backup numbers.
We used to use something that was called a de mercurafier or whatever it's really called. Worked like a mini moonshine steel. was a real thick steel container with a steel end cap about half the size of a soda can. It had a long metal rod leading to a rubber hose leading to a piece of cloth in a jar of water. We just torched the little metal container and collected the mercury out the jar afterwards. Admittedly the gold still had that dirty color afterwards so we still did the torch into a chunk of wood trick to make it a nugget afterwards.
More videos pretty please!
That’s pretty amazing. I’m in saranac lake NY and wanting to test my sluice and pans is there anywhere you suggest in Vermont or close by me.
What happened to you man
How much is one gram of gold cost?
Hello I was seeing if you still take out people with you to pan and teach them me and my cousin wanted to see if you would and how much do you charge. I goto colebrook nh alot not sure if that's close to you.
