Ive observed mine generates a large quick burp of gas as the mercury goes up in smoke,( a deeper cooler pool of water or slowed travel of that bubble may save an extra bit of the silver stuff) immediately large balls of condensed mercury get spat out the bottom.

Gidday Trent...great vid mate.... still going through the fines we crushed... have built a Ball Mill and have got my hands on some mercury...will let you know the result
@@Diggerdude29 have you ever thought about focusing the sun through a fresnel lens on the end of your retort? You can get them off old projection tvs. They make one hell of a lot of heat! Or an old sat dish or wok chromed or painted with chrome paint does as well. Any of them would require making a stand to hold them thats adjustable and the sun! You have plenty of that in AUS right?
Thanks for the video's, they keep me going on the long swings. Do you take the risk (well handled) of using mercury because it has a higher recovery capabilitiy than other methods? Do you need this higher potential because your separator bowl is very effective with small particals? I'm thinking of using the same method.
bettabgood yes mate, I've chosen this method for the very high record rate. The Knudsen bowl has a very high recovery rate if used correctly, I've found it to be 95%+. The mercury amalgam bowl is by far quickest way to guarantee you get all the micron gold. Good luck with yours.
i think i seen somewhere you can recharge your mercury by sticking two wires in it to a nine volt battery any way ,loved your vids good onya,but dont sit to close when you retort because the gas off the merc is deadly hey.
Hello Trent, Keith from the US here. Nice job on the series. Question- have you tested your tailings to see how much you are losing? Could be a little, could be a lot. I have a video on panning micro fine gold that might be useful if you haven't assayed your tails yet. Keith Bowen Hard Rock University
+Hard Rock University Gday Keith, I have tested the tailings by pan and usually struggle to find anything visible. I havent bothered assaying the tailings cause I was only interested in what that setup could recover not what a fire assay can get. Next season I will have a bigger plant with 8" jaw crusher feeding a 4 ton per hour ball mill then knudsen concentrator and shaker table. This season we will be desert alluvial mining with a 10 ton per hour dry blower. Will do some vids of that in a few weeks.
Ball mills can trap gold also Sometimes impact mills can be better for that reason. A peripheral discharge ball mill does OK. You might want to try testing some of your ore in a ball mill before buying for safety sake. The big boys are often moving such volume that nothing else make near the economic sense, but us 'little folk' have more options. You might also want to check out my video on panning micro fine gold as it might be very useful to you. Keep up the good work. Keith
Hi mate, I use the same retort and usually have mercury fines stuck to the stem of the cup- I sand it down before use and make sure it's clean, how does yours end up Cheers enjoyed the vids
Haha nice one mate! Love the way you measure time in beers!! Don't know if you will see this, was wondering how much Mercury it took to hold that 21g of gold??? Cheers
martin humphreys Glad you liked the video Martin. I had 2oz of mercury in there to begin with, most of the mercury is recovered while squeezing it through the cloth, there's only a few grams left in the amalgam when it goes to the retort.
2:20 Here's a suggestion: Next time, try lighting the fire on the far side first, so you don't risk burning your arm as you reach across the newly-lit fire.
Love your work Trent & Jacquie,got my fist piece after attending one of your course in Tuena........you are living the dream.
Only thing is uh Trent? Those pink rubber gloves? EEs no seksi! Lol

Cheers!! awesome video..from the USA
Looks like an interesting and fun process.Great video.Thumbs up from me....Cheers,Trev.
Great video. Just one thing, you should probably weigh your mercury before and after, to keep track of your losses.
Thanks for sharing. Good video clear and informative.
Nice job! Have really enjoyed your videos
I am working on a mining documentary. May I use some of this video in mine?
No worries 👍
Very nice results, great work guys.
Three beers to be sure! Lol
Nice result! Do you get most of your mercury back? Do you know the % you lose if any? Im assuming you have to lose some right?
You do lose a small amount, never measured the weight but I do notice the container going down a bees.

Great video. Where can I get mercury in Aus? Takes thousands of those little tilt switches to get any amount.
Plz ans the complete processes start to end
love your japanese safety boots mate
Thanks for posting the vid up Trent. Does the gold melt into the button? Is it a single mass of gold now?
Ben's Mis-adventures the mercury sort of dissolves the gold , so when you retort it back out it is fused into a button
I'm not a drinker but, are the three beers Fosters or Budweiser size . Time difference between size needs clarified. Stay safe and dig dirt.

i really enjoyed these videos, thanks for sharing :)
Can you leave it over night to cool
Hi mate, I use the same retort and usually have mercury fines stuck to the stem of the cup- I sand it down before use and make sure it's clean, how does yours end up Cheers enjoyed the vids
Never really noticed it anywhere except in the bottom, it is very hot where I live might make the difference.
Tell me the weight of the wood you used in this process process how much time later we put water on fire
That's excellent 👌

Gold goes 1/1 with mercury, so 21gms
Excellent. Thank you mate!
I would of made that fire a bit higher giving it more of the tube to safely recondense
ok. an idea to improve your design a bit. wrap copper tubing around the botton an pump cold water thruoght it.
Done at three beers, love it.....😃
Great video, looks like you enjoy life kudos to you....
HI Trent .. can I get the plans or link to the plans for the retort please ?
how long did you burn that over to fire
+Lloyd Carpenter 3 Beers. Incase some people dont drink at the same pace as me, about 1 hour. ;)
2:20 Here's a suggestion: Next time, try lighting the fire on the far side first, so you don't risk burning your arm as you reach across the newly-lit fire.
Hi trent tell me how many gram mercury you used in thia process i am waiting for your reply
About 2oz, 60g
Thanks for the info I have inquired
Oh and after you clean up and sit down and relax how many beers does that take...
+wally mack 1/2 a carton to relax
Mantaaap I Like 👍👍👍
Hello Trent plz send me this complete msg and any things name
