- Join Jason as he embarks on a mission to Mauritania, West Africa, to introduce mercury-free mineral processing.
This video provides an insider view at MBMM’s recent support for to a development project by the non-profit Pact, working together to demonstrate mercury-free mineral processing solutions for the artisanal and small-scale gold mining (ASGM) sector. Did you know the ASGM sector directly employs an estimated 20 million people around the world? The ‘informal’ gold sector employs more individuals than the industrial mining sector, and by a huge margin.
In this video series, Jason is providing consulting services for Pact’s development project, which is financed by the European Partnership for Responsible Minerals. Jason’s state-of-the-art mineral processing equipment is installed in Mauritania and is tested head-to-head against local methods which rely heavily on the use of toxic mercury. This unique development project approach was conceived by Pact, and through private sector partnership with Pact’s local partner Magma, and their gold focused entity named Sahel Clean Gold. Check out the weblinks below to learn more.
This video showcases the unique setup enabling mineral test-work in the ASGM context. The approach employed by the project partners enabled controlled testing and sampling methods, to directly compare the efficiency of different methods, and to design a locally adapted solution, for the Mauritanian context. Stay tuned for part two, where the final results of the study are revealed.

Thank you for your efforts to stop mercury mining.
Don’t forget their efforts to remove lead from the smelting process. Every little bit helps!
@@samsonian For sure, but the mercury is so much worse. That Kenya video with the lady wiping her face with the mercury rag and the burning of it around children really was spooky. The lead at least stays contained for the most part.
@@5in1killa yeah, I wasn’t trying to compare the two; mainly just pointing out the fact they kinda go together as far as substances that need to be cleaned up from the environment and kept away from humans/other animals…if you were to ask an eagle or other bird of prey they would be much more concerned about lead than mercury. They both combine to create quite the toxic legacy in our environment.
@@ManMountainMetals Someone has to make them. He took the initiative.
@@samsonian Yeah i tried using Bismuth and it ate up all the gold and didn't end up cupelling out!
I gave that shit like 30 minutes straight but it just stayed grey and nasty... I almost think that maybe i evaporated some of the gold ... even though that is obviously not really possible... But the material is equal to the amount of gold i put in it and still looks nothing like gold! So i have no idea how to salvage the 6 grams of high karat gold i now have alloyed with disgusting bismuth...
No thanks to people who recommend using bismuth!
Lead would have presented NO such issues...
Happy to be part of this...thanks for sharing...great things for 2024
Re: discussion @14:15, you could keep the inside track mobilized by adding a paddle, at 90 degrees from each grinding wheel, that moves the sediment back towards the center. The paddles don't need to pivot due to wear, like the wheels do, but you would want to be able to replace them periodically.
Your normal content makes you a cool guy.
Doing these mercury free projects makes you a hero.
You’re a good man Jason. I wish you every success in all your ventures 😊
Fantastic! Hope your equipment proves it's worth! Getting rid of the mercury would be great!! Thumbs up! Be safe. Jim
Wow! 5-30 g/t(!)
Very interesting. Mercury contamination from small gold mines is a serious problem for everybody so this is excellent.
Jason, thank you for trying to improve the lives of the miners in Africa, you are truly a good man.⛏⚒⛏
Awesome video Jason! I've always wanted to see how a cone mill actually worked. Silver Spike definitely likes this one.
This doesn't fall under the "wyt savior complex." You are just trying to better operations of the mines. Thank you, and Mother Nature thanks you.
Man, I hope to see the results. So great to get that mercury out of the atmosphere. Plus the local processors health....
The roller crushers are supposed to have a scraper that directs the material under the wheels. Same crushers are used to mill black powder....with brass wheels.
Before I used a kind of this mill too. To get rid of the cementation zone in the wheel crusher I installed a kind of a plow what pushes the materials continues back to the wheels track. Just a small adjustment, easy to do.
Tough situation as the mercury will be ideal for that scenario and the better money is always going to motivate the miners. Hopefully you can at least persuade them to recycle the mercury using a condenser. always recycle the mercury, super easy to do. You make good equipment Jason and i absolutely love you going over to help dial in their equipment. Fingers crossed for the results.
Very interesting, Jason! I appreciate you and everyone who has always went all over the world to help encourage, educate, and provide equipment and training for a safer environment and mining in general. I'm sure, beyond a shadow of a doubt, that these miners are so thankful to have some of the back breaking work lessen because of your machinery. Thank you so much!
Looking at the end of the two grinding stones' results, I was actually impressed. Never seen that piece of equipment before. Since the material gets right up against the middle of the machine's tray and hardens, I'm offering you some FFT (Food For Thought). 🤔 [Like Dan's GLOTD]. First suggestion would be to make the area between the stones and innermost side of the tray less steep. This might allow the material to slide down under the grinding stone. At least it would eliminate the need to dig out the harder, coarser pieces by hand. It would also help to grind everything to the same consistency.
If the first FFT is not feasible, you could weld a metal 'scraper' to the inner axle area of each grind stone. They should at least keep a lot of the material from getting stuck and push it back towards the grinding area.
I hope you and your family had a great Christmas and New Year. Blessings from Alabama ❤️
So neat to see some foreign operations! Maybe some Dawn or Jetdry for just so small the grind is. Thanks Jason!
funny Greg I commented on the jet dry notion too ...then read your comment just below mine ..oops I guess great minds think alike ha ha ha... lol
That gold said ✌️ I'm out @ 21:27, jet dry works by breaking surface tension.
This is such a wonderful thing you’re doing Jason!! I think they should also sell their gold directly to consumers and institute a system like fair trade coffee but for gold as well. They can charge a little premium over spot and be even more profitable. It would be a win-win-win for everyone! They get even higher returns and we get gold cheaper than a bullion dealer and their economies can change for the good!
Thanks for sharing, Jason. You do a magnificent job of crystal clear and scientific experimentation, expertise and results. I mean to say I truly admire your dedication to us little gold miners and keeping us up to 'speed!' So many important endeavors recorded and published. Swell Job!!
Thank You for Your time and efforts Jason. Best Wishes.
Jason, You're a beast. dude, you should totally rock the 8"pvc pipe chute, replace your wood slide ramp thing. Load directly into a wheelbarrow
Nice work mate looking after the planet and the miners 💯👌🏽
Some lengths of chain fixed to the axels of the wet pan mill might help with mixing in the cementing of material in the edges of it
Thank you Jason for sharing this awesome video with us six stars brother
Hey Jason,
Poor results for the effort, but still a good video showing the process.
The MBMM equipment is doing a great job with the low grade ore.
Thanks for making this video, keep up the good work! I tumbled some of the more promising chunks from your mine, from one of those 25lb bags. Some of the specimens are amazing, thanks.
I expected far more swamps, vampires, werewolves and haunted woods there, not sure why.
But I'm so excited to see this working. The mining in Africa has been horrific for the miners for so long now. I hope the progress continues.
Very interesting video Gents. You put in quite a bit of work for not a great amount of gold but hopefully you get the results you wanted when you get all the tests done. Good job 👍
Very Proud of your work and Traveling.... :)
I've used BORAX as a replacement for MERCURY AMALGAMATION, with Interesting Results
Awesome work Jason!
Man you get around. Thanks for another good video Jason!
wondering if there could be some sort of Surfactant like jet dry injected into the material as it is delivered onto the shaker table to help reduce the float loss if their is any ....thanks for the vids Jason
Perhaps set each wheel in the cone mill to sweep a separate path, one outside tracking, and the other inner to clear the 'cemented' area. Slide the wheel in a few inches is all you need to do.
Perhaps add another bar across the the shaft perpendicular to the wheel axel then mounting two rakes between the stones that can keep the troughs broken up?
This is a great follow-up to your previous Africa video. 👍🏻
Would a small chute/flair on the jaw crusher feed help? I feel it would direct all of the ore in and make it easier for the shoveler increasing his target area and keeping it cleaner? Wouldn’t rinsing the wheel crusher out onto the shaker table be faster, easier and the most efficient way to clear that crusher? Very cool project!
Keep up the great work inspirational
Great video...
Have they considered gold digesting bacteria as a mercury replacement? If the gold particles are too small for mechanical recovery the biological method may be a better option than chemicals. It is often used for semiconductor recycling for that reason. You may also get better results with the cone crusher running it as a continuous system. Fixing the caking should be easy though if you tack weld some kind of scraper/paddle to keep material from settling there. Even a ring of blades acting as impellers to circulate the material towards the wheels could improve grinding speed.
You are a god send for up and comers!!!!
Dang Jason, you're up early. No jet dry in your panning water? Would it benefit to add jet dry to the shaker table as well to break surface tension and prevent the gold from floating into the #4 tailings?
HOT DAMN! Mornin, Jason! Happy saturday! GOOOOOOOLDDD!!!!!
Once the best way of gold recovery is found they will be profitable. Great Teamwork Jason. 👍💕🙏
Thanks for what you do !!
I hope it works the way it should!! Breathing that stuff is NOT good!! Have a great week!
Good job bro 👍
Really interesting vid.
Way cool, Good luck!
That's awesome man! Heck yeah
Really great work Jason!
Now with the track scrapers. If they can attach a couple belt magnets so it picks up the magnetics drop it back on the table a couple times so if it picked up gold with the first lift it gives the gold a chance to drop out
I saw something that looked like the two big round stones at the REED gold mine just east of Charlotte, NC. That area was a very big gold mining operation from 1800-1849.
22:00 Makes me wonder if the miners didn't hand-pick poor quality ore for you to smelt.
That wheel mill just makes makes the gold way small and as you see in your pan float. Perfect set up for mercury but counterproductive for the shaker table.
My guess your recovery next week with mercury will be much higher.
I would be interested to see how going straight from the hammer mill to the table would work.
Interesting video, thanks
The cone grinder should have paddles that moves the sediment away from the inside edge
The other way to keep the center of that cone mill clear would be to have a hydraulic system that's a spray bar that has jets shooting down washing the material away from that central hub. The downside to that is it'd use a lot more water which they obviously don't have.
Awesome!
Love your work.... Still waiting for the video when you really get into the ore bags out of YOUR mine....
That cone mill needs deflection plates that scrape and push material from the inside towards the center path of the roller wheels.
Isn't that wet mill called a concher or a melangeur? Mr. Hershey used this type to make chocolate. The original design goes back to the early 1800s and is the machine that made chocolate available to the masses.
Thank you. Keep working!
Just watching this video made me feel like I had to sneeze!
Great job. Just wondering why you didn’t manufacture a safety cover for that cone mill belt drive? Rest of the machine looks pretty nice!👍
Yo that's awesome I love you guys

Richest gold fields in the world way back in the day.
I would like to see a video on gold ore floation using pine oil. The very little bit I can find on the Internet says you can use a drill press to stir and a fish tank bubbler to froth with pine oil or terpintine for the agent? Nobody is on the topic of froth flotation. Can you make a video on that? Thanks Aaron
Did the Gold start to float on the shaker table and went with the tailings?
7:43 ... I was just imagining, instead of fines with a little gold in it?? ... If only that square yellow bucket was pure gold dust instead !! :) LOL
Had an idea on the cone mill, what if you had adjustable scrapers that you could move up and down between the stones to occasionally scrape it off the bottom so you don’t have to do it so much at the end.
Very cool
13:25 Watch some videos on sand mullers. They are used to mix sand and water or oil for casting metals and have a wheel/paddle combination like he's describing.
Where does the steel come from? Is that from the jaw crusher?
Oh, good, Mauritania hasn't changed location.
So cool!
Hey Jason. Love your videos. I got an idea for the design of your cone mill. Make deep ruts as thick as the wheels and recycled pressurized sprayers to keep the ore moving. I'm thinking Lee's maintenance and better finish for crushing ore. What do you guys think. Thanks again.
🇨🇦😎👍
"Non profit gold" yeeey 🎉
curious for the waste water reclamation, how do you keep it from becoming an mosquito breeding pool? The water looked pretty dank.
There's the guy.. back to some MBMM
all that steel came from what? the cone mill?
Very interesting but ..... did Wagner pmc abscond with the better grade material
I was wondering Jason when was this filmed?
feb 2023
Would it be worth adding a bit of soap to the cone mill and the water going over the shaker table to see if hydrophobia is affecting them?
What are the wheels made of? In the Arista and are they repurposed from another use or made esp for this use? Thankyou
Congratulations Jason on being global. Hope you left them your MBMM coin. Akerace Drill
if you put that magnet in a plastic bag its much easier to clean that is of course if you have one around. how much power does the whole system use per ton of ore?
Thats so cool i loke your videos
3:13 can you please tell that guy we all say hi back
89 👍's up mbmllc thank you for sharing 😅
Why does it have steel in it?
From the steel body of the cone mill. The stone wheels wear away the bottom of the mill.
@@xenaguy01 oh gotcha! Yeah that makes sense! Shoulda thought of that one prolly. 😂 does that seem like it’s wearing out fast then? Quite a bit there it looked like? Could be new and breaking in too I suppose?
everything there looks like it was sitting there for quite some time before your arrival
Why would that cone mill be needed at all when you don't use one at home? You don't use one at home. Im just wondering is it just because of how they had it set up? Could you convince them to take it would and hook the hammer mill up to the shaker table like you have it at your place?
We tried hammer mill only and grind size not fine enough. This is a typical case quartz veins with high proportion of very fine gold. See report link in next video. We decided to adapt cone Mills in our solution because they are already in widespread use in Mauritania.
I'm trying to figure out if a continuity check with my meter on pyrite ore works. Some more it works with and some more doesn't pass the test. The ore that doesn't sound off still leaves a clear voltage but not enough to pass the continuity check. Is there anything to this and if so would you make a video on it? Thanks. As always I like, share and subscribe
So Cool
50 cycle electricity there?
Did you use a 50 cycle
motor or a VFD with your normal us 60 cycle motor ?
:03
confused? Only place I know named Mt. Baker is in washington? Its a volcanoe?
yes he's located in Washington
👍
Do they retork the mercury?
no, retorts are not common in mauritania
@@dstap it only makes me wonder why not? The heat needed to burn off mercury is the same needed to reclaim the mercury vapor and then use it again and again.

You know that you're in Artisanal mining country when you start seeing Chilean Molinos (cone mills.)
