Topic thread for very fine material handling ether dry or wet presses.

The gold cube, shaker table, electrostatic, miller table processes come to mind for this thread topic. However there may be other process as well that I have not pointed out here.

Thanks for anyone's inputs.

A rotating trommel screen that had a blower for self cleaning could work well for very fine materials wet or dry.

Anyone use a electrostatic process with a trommel screens?
Thank you.

It would be easy to have one screen inside of the other with different polarity charge using DC. volts and just adjusted the current to give the results you want with different sized / screened materials for each run or batch of materials.

Assembler, you're going to have to have a really large surface area to screen down to 200 mesh. Otherwise you will find you have a REALLY slow feed rate. Also, a screen that fine will be fragile....you'll have to pre-screen to a near size before running material over it. If you get it figured out, I hope you'll post some video or pics.
Best,
Jim

Yep that's why you are not seeing much information about this on this forum in general.
I would not even consider doing this if you do not have say a 30,000 volt DC. meter and tools to handle this in a safer way. A older BK meter works well that is a analog type.

I'm starting with 2 - 13" x 36" long screens to help get enough surface area before plunging up......lol.

This is a very fine operation so the whole process is to be slowed down. That's ok as there is a whole lot less shoveling going on to start with as this will be for just rock.

I should point out that maybe a air blower may speed up the operation by helping to unplug the screens as they go around,

Anyone who starts to put this together will be way ahead of the crowd when it comes to hard rock......lol.

This will help some to start thinking about current with the pressure of the volts going on.

Some minerals naturally like to go with the flow of current.........pun intended.......lol.

Minus 200 mesh ? You'll need a TON of it amount to anything ???

Thinking a hair blower would just blow it away .Minus 200 is like baby powder

Not if most of the minerals you are after is clinging very strongly to the screen / belt/ plate that is charged enough.

Yes this is what crushing rock is about and it is no problem. A lot of people will have at least some of the rock below the 200 mesh size so what do you do with it...........lol.

Yeah but if 'other minerals' are clinging to the gold its no longer minus 200 mesh ???

Minus 100 is just about as small as I go.And a home made Miller catches it just fine:)

Gold for example will prefer the stronger charge over the weak iron charge that is from the ground or even other minerals. Natures events often can come to play here. Nature has no problem with large voltage and amperage just take a look at lightning for example.

Yep I agree as most people can not pan past around 180 mesh. This is not for everyone that is for sure.

If you happen to have a number of tons to handle this is a different factor all together.

Having a lot of material that is say from 400 to 180 mesh can really add up. Always best to screen this into different sizes first.
