Urban Mining for Gold. Processing Circuit boards with a hammer mill and shaker table 

Haha, I never really thought of it that way, but you make a good point.

Gavin Helgeson I love that explanation!

great comment. reminds me of Parting of the sensory by modest mouse as a metaphic and the exposition as a plus..

NICE analogy haha

That is, it turns out that do you think quantum computers will thresh only digital machines?)

Thank you for your comment and for watching our videos!

Thanks Kevin. Hope you are doing well.

Thank you for your comment and for watching our videos!

+Ask Jeff Williams Thanks! Always great to get kudos from Jeff and Slim!

you betcha my friend, me and Slim have always like watching your set up and really like how you have an on site Recycler for Base metals and precious metals from PC boards. Real nice set up. Jeff and Slim

you betcha my friend. Jeff and Slim

What he is saying is that Slim will probably try to sneak in there and run some of Jeff's ore for free...then head on over to the Saloon to watch the girls dance and pay them in nuggets.

Great! Thanks!

+Jan M. Thanks! More on the way...

@@mbmmllc Sir i wont to know detect,,, for youe machine,, zahidmd605@gmail

Hi. All great ideas. We haven't done much with the tailings yet, but we are always looking for ways to re use things. Thanks

+corsagafa Thanks for the tips! I will check out your video. Thanks

+Dumpster Marcus As of now I am not sure. The customer was going to have it analyzed and he said he would get back to me. I will let you know as soon as I hear what values he recovered. Thanks

Great! Thanks!

Great! Thanks!

Thanks!

That is a great question. People do lots of different stuff. Some people refine it themselves, others send it off to a refiner. There are lots of different ways to go about refining the material and it really depends on what you are after. I am working on a new video to show a way to refine the material and get your PM's and copper out. Stay tuned.

Get about 3.5 oz/ton gold and around 30% copper

+angryadrien Hello and thanks for your question. We have sent these off for analysis and hope to hear something back in the next few weeks. I will keep you posted when we hear something. Thanks

Have you posted the results yet?

@@angryadrien Not yet.

@@filonin2 bummer

Great! Thanks!

Thanks!

I believe he said it was roughly 25-50 pounds of boards. He has stated in other comments that the set up can run about 200-400 pounds per hour and was around 85% gold recovered. The assay results video broke it down and figured there is roughly 4.5 Toz gold per ton. At today's rate, 11/07/20, that's about $8500 per ton, just of gold..

about 3 oz gold, 15 oz silver, and 30% copper by weight

Hi. We do have a smaller system that some of our clients are using in their small shop or garage. Please send us an email at MBMMLLC@gmail.com for more info. Thanks

We sell a small impact mill, can do 250 lbs. + an hour, real good on IC chips. $1,695. Use one ourselves. We do small scale but planning to up the volume.

@@maranti34b can you provide a link? I'm really interested

We ran around 25-50 pounds of boards for this video.

@@mbmmllc planning a trip out to see you guys this Sept. 2019. Look forward to seeing the set up and possibly running a sample. Will be in touch later in July or early August. Keep doing what you do.

thats what i would like to know as well .......

Thanks for you question. This machine is not meant to separate the gold plating from the other metals. This machine is designed to remove the metals from the boards which can later be processed to remove the precious metals. We have tested the tailings/waste from the board grinder and currently we are recovering about 85% of the gold, 90% of the silver and other PMs and much higher percentages of base metals. We are working to improve our hydrocyclone design to get a higher recovery of the gold and other PMs. Thanks

Id like to see your testing and waste - uh use or disposal

@@mbmmllc Great points and excellent stats one just one part of a overall recovery system - the Table is the Rougher, Smelting will recover the remaining.

@@mbmmllc price?

Hi Andy. Actually in 1 ton of PCB at today's prices there is about $20,000 USD in metal value! This stuff will be the new ore mined in the future for sure!

Their profit is is mostly from customers who pay to have this done and or the RU-vid monetization provided from this and other videos. So like and subscribe then hit the bell...if you don't feel like donating. Might be a couple ways to profit.

Yes it can do both. The metals are where the money is though

We did not conduct a assay on this particular test. It was to just demonstrate how our hammer mill and shaker table can process PCBs. Here is a link to the assay results we had done on a much larger sample. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ReOQ1uFvsZs.html

Can't remember, it was a long time ago :)

BAZXXXBEST shhhhhhhh, grownups are talking.

@@TaintedMojo LOL!

@BAZXXXBEST THAT IS RUDE! and NOT NECESSARY.

@BAZXXXBEST wow dude, I was just going to ask you how much gold you recovered 4 years ago, but I guess we already know..

Great, thanks for the tip!

Ideally sell to a refiner

Hi. It will really depend on the size of the hammer mill, screen size, material, etc. For boards through a system like this you are looking at something around 500-1000 pounds per hour or so. If you are interested in more details please send us an email at MBMMLLC@gmail.com or give us a call at 360-595-4445. Thanks

We dont custom process, just sell machinery

Hi. I see you sent an email to us. I will respond with all the info to you shortly. Thanks for your interest

+fuddrucker74 Those are great questions. It will really determine the types of boards your are running. They are quite varied depending on the type of board you are processing. Mother boards have somewhere around 3-5 oz gold, 15-30 oz silver, and about 500 lbs of copper per ton of boards. Thanks

+mbmmllc ok, thank you. I needed some context to wrap my head around. thank you for the quick reply.

hello, thanx for the video , do you also separate palladium and platinum ?, greetings

+thibaud can lidth Yes our shaker table does separate palladium and platinum, the majority of both will go into the number one port and the remaining will go into the number two port.

oke thanx! keep up the good work guys!

Baah! It keeps the liver occupied.

Burning is not a good solution, probably just sell them on boardsort.com or something

How about in pesos ? LOL

@@mbmmllc I liked your wet hammermill with the wet shaker table. You ever think about doing car batteries? Drain asid. Add LOTS of baking soda to the water. Seberate lead and plastic.

Hello. Yes this can be done with memory cards and RAM. I see you have already send us an email so I will respond with more detail through email. Thanks

They take only the free gold. The fact that the plastic goes in the garbage. Hydrochloridebuy need a large volume.

Hello how are you, we talked a few months ago, would you have facebook so we can chat, thank you

Felippe, once you have concentrated the precious metals in the number one and two ports you will need to refine the concentrates yourself or send them off to a refiner to do it for you.

I think this way for recover precious metals is good, becouse is fast and dont use any chemicals materials. This process get 100% of precious metals? Congratulations! I would like to use this technology in my country. Thank you.

Not great

Thanks for the comment. Right now its just worth the metals. Thanks

Hi Bob. Thanks for your comment. The magnetic cross belt used in this video is not recommended for use with circuit boards. This is our recycling line and primarily used for separating ferrous and non-ferrous metals. I wanted to show the larger 24"x16" hammer mill and discharge conveyor as a pre-chopper for some of the larger circuit boards. You are also correct that this machine is not designed to remove the plated gold from the other metals. There is quite a bit of free gold that can be liberated from the chips and other components and recovered on the table, but most of the gold plating stays on the base metals. Notice at about 6:33 all the gold plated pins going into the #1 & #2 high grade buckets. The goal with this system is to concentrate and separate the metallics from the plastic and waste board materials. As you can see at the end of the video the results are almost 100% metal free from contamination. By screening and re-running the #1 on the table you can get a pretty clean gold product that can be melted down and sold directly. The remaining values in silver, copper, gold plating, etc. need to be sent off or refined in house to recover the rest of the metal values. Refiners will pay a much higher amount for these metallic fractions off the table than whole boards themselves. We have run several assay tests of the boards and waste material and have determined that we are actually recovering about 85% of the gold and silver values by using this method. We have found that mother boards have somewhere around 3-5 oz gold, 15-30 oz silver, and about 500 lbs of copper per ton of boards. Stay tuned for more vids. Thanks

"...not recommended for use with circuit boards." I'm seeing you putting MB and other type of circuit boards into your machine. And that magnetic separator, you are gonna get a lot of good and bad stuff picked up. The only best way to process circuit board is my hand. Otherwise, a lot of goodies gets into the trash.

Thanks for watching! Make sure to watch out for our next video!

Yeah, but catchy😂
