Regrinding Gold Tailings In A Mini Ball Mill! Better Recovery & More Gold??

[@TheWolfster001]

Adding some soap helps recover extremally fine gold, you want just enough soap to break the surface tension of the water, not so much that it has suds in it.. Adding Jet dry is better yet...

[@excitedbox5705]

water softener and detergent is what you want. As you said lower surface tension so it can drop down

[@VendettaProspecting]

What a fantastic early morning coffee and MBMMLLC

[@mbmmllc]

Awesome! Thank you

[@ursamines7643]

I love how Jason/MBMM continuously looks for better ways to improve the process.

[@mbmmllc]

Thank you!

[@Slavicplayer251]

@@mbmmllc have you thought about using leaching to get the gold instead?

[@chaosir3677]

If it's in there he's going to get it! If anything was lost, Jason always knows how much.

[@UtahGold]

Keep em coming man. I am trying to recreate some of your results. Couldn’t do it without your videos. The books on this stuff are hard to follow.

[@mbmmllc]

Thanks! Will do!

[@ToddDunning]

Best gold recovery channel on KZbin

[@jethrodigger]

Easily the best channel on KZbin for gold recovery systems explanations and practical testing, Not a sixgun or a talking skeleton in sight. Just piles of gold laden sands and machinery that actually works.

[@proaudiohd]

For real, there are some annoying personalities out there. This guy is straight facts.

[@ridingwithcharley6821]

I think you are the first guy on KZbin to turn sand into clay...lol. awesome. Thanks for doing these videos. The effort is appreciated.

[@snoozin99]

Wow, brother, that is one amazing video! So if you get 900.00 more in gold at 60.00 a gram that's some seriously big numbers for just grinding them down to a smaller amount. I was absolutely amazed at the size of your bead at the end for just a 50lb bucket of tailings. I can see now why the major mines go after the small stuff. This was one of my favorite videos that you have done, it's just mind-blowing to me, Awesome Job! Keep up the awesome work brother, this was a homerun for you for sure. :)

[@mbmmllc]

Thanks!

[@chrissaucier9386]

Awesome recovery for what would normally just get discarded. That's why it's a good idea to sample mine tailings. Half ozt per ton of material already to be processed. Nothing to turn your nose up too !!!

[@daz41262010]

pretty significant amount of gold to produce :) good job Jason :)

[@bryanjohnson9800]

Always enjoy watching your videos from here in the UK. Happy Fathers day BTW!

[@mbmmllc]

Thank you!

[@paulcoover9197]

Hey Jason, Take a look at our buddy here.. Super fine recovery method . His name is Aussie Bloke Prospector. You guys are top shelf. I told my brother about MBMMLLC today. I'm trying to spank some platina here. God Bless America and the world.

[@richardoconnor7162]

Jason there is non toxic leaching formulas out there , check out Action Mining.If you take some of your cons from the panning what you just ran from the ball mill, say 100 grams, soak in Aqua Regia over night, then do a Stanis Cloride test on the fluid the color of black will tell you there is gold left for recovery.

[@xxxm981]

You will still have to do water works with Aqua Regia. First you have to neutralize it, and then you have to distill out the salts.

[@josephpecoul6532]

You really are on something there!Great!

[@drfill9210]

You can use stokes law to figure out settling times. If all your particles are the same size then just dump them in a column of water and pour off the solution at the time the gold hits the bottom.

[@willgriffin3490]

Outstanding video! Thanks for the explanations and showing how to do these samples!

[@mbmmllc]

Glad it was helpful!

[@labandonaldhock80]

This is a fabulous education

[@drubradley8821]

HECK YES!!!! I did not expect to see that much.. well done!!!

[@bulwynkl]

There is a gold field here in West Central Victoria near Percidale where the gold is hosted in pyrite (Ordovician deep marine black smoker) - About half the gold is too fine to settle by density alone. In the same area there are rich reefs with much larger grain gold and nuggets to several hundred ounces - derived from hydrothermal veins (likely originating from the same sulphide source, but moved) So depending on the nature of the gold you are processing, your requirements will change. Knowledge is power.

[@MrDavePed]

Add a little soap to your water to virtually eliminate the surface tension.

[@frantiseklaluch6605]

Hi Jason, 15 g/ton...nice... very nice... I am sure, some people (like me) coud pay YOU some money, so they can work on that tailings for couple of days and learn something... Unfortunately I live in Czech Rep... I hope you will come here soon again...

[@comptegoogle511]

If the gold particle is to fine the surface tension of the water will make it float of the shaking table.

[@placertools3529]

Excellent video. Thanks for the lesson.

[@sharkscrapper]

Fascinating - thank you

[@mbmmllc]

Glad you enjoyed it

[@drfill9210]

Back of envelope calculation gives Max water weight at 15 pounds per 100. Half that is reasonable so 7 pounds extra is in the ballpark

[@orsud1890]

Excellent résultat

[@rawdawgpendants5490]

I love how people ask such technical questions, how many pounds did you use, how much electricity was used, did you eat breakfast, and how much gold did ya get? Like any of them will ever do this. I love a good laugh.

[@johneaton4364]

as long as they are polite, who knows? They might get The Bug!!

[@stanleykongmanmathis1065]

Very educational...love the videos and keep on digging 👌

[@gingerdude94]

The perfect start to the day

[@dn2817]

I was just curious about why one leaves a thumbs down? Were you expecting Jason to be wearing a massive gold chain at the end of the video or something?

[@danielsestina6457]

Awesome video as always. I'm definitely curious about what to do with the spent ball mill tailings. I Have worked in the concrete industry for about 20 years, and wondered about possible applications

[@frankgaletzka8477]

Hello Sir Use a ballmill with metal bares inside . So the Balls get carried up and smash Down it is called cascademoving

[@MegaZidzid]

That fine washed sand seems great for aquarium

[@johnarchuleta9893]

Jason your the man!

[@djblackprincecdn]

If you get some large metal pans and an oven that can maintain 110C then you can bake all your material for a few hours to remove all the water from it. There's even an ASTM standard for it.

[@SovereignSaurus]

Thanks for sharing! Really interesting and detailed yet the way you explain everything is easy to understand despite me not having mining or refining experience. I wonder how much gold has been retrieved from mines but remains in waste piles or tailing piles around the world

[@dean4939]

Old tailing piles are always being reworked around known mine tailing piles. As technology improved more gold became easier to process and recover, The hard part is to identify an original tailings pile which after 100 years has large trees growing thru it. Those are the better piles to rework as the original miners were going after the really rich ores and left much to waste since it was not worth the effort or because of the remoteness of the mine not worth the effort to bring it to the mill. Even back then it was down and dirty get it and get as much as you can as quick as you can and get out. Hence the reason for so many abandoned mines my guess is they were getting shut down by the government and wanted to get what they could before the workers were forced to enlist or conscripted. The government banned " non-essential " materials, like gold and silver and precious gems during world war 1. Other reasons for gold mines closing/ abandoned are the discovery of the Comstock lode, the Sherman Silver Purchase Act, and the Pittman Act all increased silver demand making it worth more than gold. Lots of abandoned mine videos with the shovel and pick still leaning against the wall, like the miners just walked and never returned. not to mention the equipment they left behind.

[@SaltyPirate71]

So, assuming a limited budget, run the turn-key system with the hammer mill until it pays for itself. Save your tailings and invest in a ball mill and rerun your tailings to loop back through your shaker table.

[@CORNDODGER]

So like 45.000 Dollars Later you get 2 grams of Gold Kinda how our Govt works!!!!

[@mbmmllc]

Exactly. Save up your tailings and if in this example you had another $850 recoverable gold per ton once you had 100 tons saved up it would be equivalent to $85,000 worth of extra gold to recover with a ball mill. The ROI on that is great!

[@bartcalder2791]

If the ball mill was at a slight angle, wouldn't the gold settle to the low end?

[@shaneyork300]

It was a valuable test! Have a Great Day!!

[@josephcormier5974]

Nice video thank you two thumbs

[@nomana60]

I'v had to grind and ball mill my material down to about -200 because thats how small the majority of my gold is. painfully slow as i can only do #40 in 24 hrs. I'm really liking the action in the ballmill you used!

[@excitedbox5705]

15g per ton is more than many mines get from their entire ore. I hope you know where you have been dumping your tailings.

[@michaeldomansky8497]

Could you use a row of Neodymium magnets under the shaker table to slow/divert metallic gold?

[@VestigialHead]

I guess if the gold had other metals in it this might work. But would probably just attract a lot of the black sand.

[@kencarbon2346]

Enjoyed watching your video nice work keep digging.🙂

[@mbmmllc]

Glad you enjoyed

[@carlreed3571]

HELLO JASON 👋

[@tonyoliver4920]

Might need to clean the spiral classifier You might have gold trapped in the caked on mud

[@xenaguy01]

It has been cleaned. If you watch older videos, you can see there is a lot of muck left in it, but now it's pretty clean. For their purposes, it doesn't matter that much, as those are tailings, not recovery. Any 20 pounds or so of crud remaining in the spiral classifier will not hold more than about 1/10 gram of gold, which will be recovered later anyway.

[@conradlowenstein9210]

For an appropriate test everything should be very clean.

[@Ross-2077]

Thats significant, looks like extra work but hopefully for you operation its worth the extra labour

[@heathstott]

Well I’m in an alluvial type area, that was top notch info, thanks Jason. Could you possibly let me know where to get good cheap cupels, I’m in Australia other than E bay there are few options,..this would be a great help and thanks for all you do on this channel. Much appreciated 🇦🇺👍

[@dodgeit3014]

Man I wish I didn’t live in Tennessee. Would love to get into something with gold.

[@GrooberNedJardine]

Great vid Jason , looks like it would be worth the effort , and if it was me i can't stand the thought of throwing gold away , no matter how much i gotta do to recover it , lol .

[@OnsloVest]

Nice effort

[@marvinforney5082]

It's all good

[@jamessmith530]

Your back this week good luck guys

[@spudnikholyghostroller7314]

The Chinese were able to catch that 1000 mesh gold in the 1800 Era by using charcoal.

[@brianteed7390]

Would a ball mill be good for re-processing tailings piles left by the old time dredges?

[@sdspivey]

Try blowing some light air through the ball mill. The really fine dust could be blown out, leaving the heavier material.

[@youssefberady]

you are a master in your field. you have some nice sand at the end, you should find a use for it.

[@dizzious]

Wow there's more gold in those tailings than there was in the virgin riverbed that I used to pan back east.

[@stormrunner0029]

Your future video with the plastic on the table to keep the gold down may be an excellent option for all grinds as well as fine grind.

[@kbaan]

I'd think if you were continuous flow wet milling w that vibratory mill and wet screened with a fine mesh screener or a wet cyclone your efficiency would go way up - just like a large gold mine.

[@goldradium77]

Love itmate hi fom Victoria Australia🇺🇸🇦🇺👌

[@snarky_user]

And, do the tailings following the ball mill have and economic value as processed material? If you could recover most of the cost of your ball mill operation by selling stone flour to industry, that would be a win.

[@stanburton6224]

If you line the bottom of your auger trough with sheets of rubber, you'd keep from forming a layer of sand/clay between the auger and the trough.

[@xenaguy01]

You'd also create a hiding place for small material between the trough and the rubber.

[@74KU]

7:00 why not feed the ball mill back into the primary shaker and use baffles to classify/remove the oversize based on flow? I'm sure I have not given it as much though as you though.

[@kramhoogness]

Have you found gold locked in the structure of the sulfides? That would be interesting to test someone.

[@nathanielpontinovitz4698]

I breath dust . The dust keeps helping my body grow.

[@Jkauppa]

rotary centrifugal separator instead of in addition to the shaker, centrifugal "shaker", spin, can have tons of centrifugal force gravity

[@Jkauppa]

shaker ball mill, linear actuator, rotary to linear slider, ie, piston ball mill in cylinders

[@Jkauppa]

scanning electron microscope with x-ray concentration determination

[@shawnsparkman7916]

What about a centrifuge system for catching gold?

[@mikeconnery4652]

Great video there is always something I want to know about and this was one of those things. Thank you

[@cziprick]

So that worked out to be around $600 per ton. That's not too bad!

[@kallakrastev769]

Hi, Jason! Couldn't you just increese the angle of the screw transporter before the ballmill. Put the same ballmill upper level also and to return the fine sand in the same shaking table? . 🤔

[@spudnikholyghostroller7314]

I'm not into chemicals either but between air dry liquid soap and charcoal and mercury.I've be able to catch 1000 mesh gold

[@johncarter6688]

Great video… excellent job of explaining your processes and teaching the skills to the world… I also believe you are still marginally above the point of diminishing returns… pulling 13.5 grams a ton at today’s market price is right at $750 profit per ton… I don’t know what the cost of your operations run to conduct the extra processing per ton but I’d guess it’s below that mark… and if a test sample is done prior to first run processing then it could be even more cost effective because then it could be a modified system first time around and not two totally separate processes…. Thank you for your excellent video.

[@Gainn]

Half-ounce extra per ton is quite a boost.

[@lazyjackass77]

really good video thank you for all your hard work

[@MrDavePed]

Why don't you use a centrifuge for the fine stuff? It is like multiplying the gravity.

[@Woodie-xq1ew]

When you were talking about the smaller particles having issues separating properly on the shaker table I had an idea. I’m sure you have, but have you done a test to see if varying the frequency and amplitude of the vibration on the table affects separation? And whether the efficiency can be improved with a finer material by changing these parameters?

[@bretnielsen5502]

Always interesting !!!!

[@mbmmllc]

Thanks!

[@joshredding9588]

great info!

[@mbmmllc]

Thanks for watching!

[@FunDumb]

It would be fun to experiment with some bubblers as well in that bucket. Then test if really need to shaker the contents of the entire bucket or just the latter 10%.

[@xenaguy01]

This sounds like a great idea!

[@mbmmllc]

Good idea!

[@kalimantangemstone]

Good

[@professortrog7742]

You could loop the out-port of the ballmill directly back onto the shakertable.

[@xenaguy01]

He said (and I agree) better to run to a second shaker table, tuned for 200- mesh material.

[@saschachloriana4177]

Or better yet, a slimes table.

[@jcadult101]

Agree with what you said about finding out up front how much can be liberated. But you also have to factor in labor and equipment cost, no? You had to gather, and load the ball mill then run it for an hour. If you liberate a lot, but not enough to pay for the electricity to run that huge motor, let alone your time/cost shoveling it in and out 5 gallons at a time and moving the material around, is it still worth it?

[@joel383]

Might just be iron filings from the mill too

[@GordonDouglas-rc3nq]

Have you ever used charcoal to catch the 500 mesh up and more it will catch it that is how the Chinese did it in the 1800s they were catching the gold that floated

[@Sven-_Trials]

I'm surprised at the amount gold in the tailings!

[@mbmmllc]

Me too!

[@BESHYSBEES]

Can you rub the gold button on some super fine wet n dry and do acid test to determine purity? Seems like a lot of work but 15g a tonne could make it worth the time and effort. And as some one else mentioned some dish soap will help drop the fine gold

[@lonjohnson5161]

After pulverizing in the ball mill, you could take what is left and convert it into bricks. I don't know if it would be profitable, but it seems a shame to process the ore so much have have to dump it in a hole somewhere.

[@mbmmllc]

I have thought the same thing too

[@georgehanson1658]

Good job!

[@heapsofspace759]

I was very interested in all that you are good at your job man . Makes me think of a couple of places now. Golds in the sand but you carnt see it. Cheers

You have missed the point of these systems. He doesn't want to use those traditional, harmful chemicals.

[@pnwprospecting]

Is bismuth better for small amounts over lead?

[@rauliprunnila1365]

could this ballmill itself or first hammermill and then ballmill separate metals out of electric waste? It would be interesting if you could mill for example old computer parts this small and then separate valuable metals without cemicals this way?

[@mbmmllc]

Yes, I would like to do a video grinding IC chips in it

[@samwood2769]

Jason, can you do a video on extracting the silver from the used cupels?

[@TrevsOutbackandGoldAdventures]

I have just gone back and reviewed your video on regrinding black sands,and by comparison it would seem the tailing sands seemed to yield a better result than the sulphides. Question One/..Could this indicate that there is more bound gold in the quartz ,and/or other rock, in the sands ,than gold bound to sulphides in your number one and two tailings? Question 2/...Would it be worth an examination under the microscope of grains in your sulphides and grains in your sands to see if bound gold can actually be seen? Question 3/...I looked to me that you got a better result in this video by grinding dry than in the previous video grinding wet material. Would you agree with that? Cheers.

[@deweydoesdaily742]

How would a ball mill fit in the turn key system would it be opened ended with a screen and how fast could the out put be could it keep up with the whole system at full throttle

[@piousminion7822]

Looks like you're going to get a lot of "iron" in your mix using the ball mill. lol

[@adventuresofaliftime4989]

Hey if there isn't enough gd to be worth processing the tailings they're still worth something for use like clean classified paver sand.
