Shaker Table

I recently made a post regarding the recovery of copper from some ram boards, after the chips have been removed feed the boards through a hammer mill to liberate the copper. then pass the pulp over a shaker table to separate the copper.

The shaker table in the video is used to separate the undersized oysters holding these back at the nursery with the larger ones relocated to the beds in which they will mature.

The offset that oscillates the table was a short piece cut from the shaft then welded back onto the shaft with a slight offset.

Pretty cool idea that simplifies the build, shaker tables have a multitude of uses. This table design maybe modified to suit most needs.

Recently processed this sample that came from an ancient river bottom, now that the base metals have been removed I have some promising material that needs an assay to reveal the contents left behind in the black sand.

My shaker table is a lot differnt than your's but we use it for several differnt thing's. Sorting brass, yellow brass, red brass, al bronze brass, semi red, 360 rod solid's, ammo, we get a lot of ammo and must sort out the Al, steel and live round's, I have one customer that mix's there 201 stainless with there bushling clip, the magnet pull's the bushling out and let's the 201 fall into a tipper cart. I'll get some pic's and post later.

Waiting for those pics

A black precipitate has collected onto the copper, which means there are precious metals present from the ancient river bottom sample, this sample was removed from the first two feet of overburden. now my summer project is to reach bedrock.

For anyone interested look at this video, you can build your own for 20-30$ with scrap and a hand sander:
https://www.youtube.com/watch?v=aGPXcu3OsEk

The precipitate in the filter paper is from a one pound sample I've been playing with, the precipitate is still wet but you can still clearly see the brown powder along with some blacks.

The black sand left over from the cold leach shows promise of some platinum metals, again only an assay is going to reveal the truth. The black sand has a grain size large enough for a centrifuge recovery.

I found a laboratory close by that will do my assay at a reasonable cost.

Hopefully there's enough gold in this material to warrant setting up a flotation cell.

Need help, the dried filter paper weighs .3 grams heavier than an unused one, using the .3 as a baseline how many grams of precious metals would there be in a metric ton 2200 lbs.

Thanks.

1,000,000 grams in a metric ton Eh, all I want is 672 of them grams per ton. That my friend would be 21.60 troy ounces of gold valued at $24,295.03 American dollars per metric ton.

Lately my luck don’t run that way, so I'm going to process another sample from this batch before breaking out the champaign.

How much did your sample dirt weigh? If your sample dirt was 1 kilogram, 1000 grams, and you recovered .3 grams of precious metals from 1000 grams, then... 1 metric ton, 1,000,000 grams would yield 300 grams precious metals or 10.71 oz. (not troy, not sure the conversion)

The water table better known as the shaker table has been in use in the mining industry for well over a hundred years, I believe the fist tables were manufactured by Wilfley his patent run out years ago today many tables bearing his name are still manufactured using his original design also many clones using different mechanical means to obtain the shaking motion are being offered on the market.

https://www.google.ca/search?client=...C5Pj-QOGjpT4CA

Also there are many DIY plans to build your own table available on the Internet.

Someone here on the forum posted they were looking for a water table, I did not know WTF they were actually looking for, the table they want is a shaker table AKA Wilfley Table.

The shaker table does a great job of separating materials having different specific gravity’s such as granulated copper contaminated with plastic chops. The problem is that the tables have a large foot print and can be troublesome to set up,plus they require a solid base like a concrete floor.

For my purposes I'm going to use a small 12 inch centrifuge which is capable of out performing the shaker table by several hundred times, that small 12 inch centrifuge can process 160 pounds a minute while it would take a medium sized table 10 minutes or more to process the same amount of material.

The centrifuge has a small footprint and needs to fine tuning to operate efficiently, the downside is that a centrifuge is going to cost ten times more than a shaker table would..

12 inch centrifuge sounds like the old 'milk and cream seperator'. Great fun as a kid.
Put a little tab of cardboard in the spindle and wind the thing up and suddenly the cardboard lets go and fly's up into the air like a rocket powered helecopter.

The winding lever was because it was hand powered and the spindle normally had a bunch of bowls on it for separating the cream out.

Near where I live there's Gold mine remains from last century and early this one.
Stampers for quartz, big centrifuges. Little huts and buildings, water races and old water pipes.
When Gold busted in the 'States, miners travelled here to try it out. Lots of Chinese too.

A lot of its accessible by motorbike and when Dad met up with a old workmate who had brought a Honda XR250.....
Next thing we were riding them too. Often had 10-15 people all on Hondas riding all sorts of trails in all sorts of places.
For you 'lord of the rings' people. Google image 'Arrow river - Arrowtown'. That's a Gold town and access point to many more Gold towns, also a LOTR film location spot, there's a huge wall of water rushes down that valley in the film.
Funny because in real life there's no way it could happen, and if it did, it would wipe out the township 200yards behind it. (A friend worked on that movie, and others Sir Peters done)

You can pan there and get specks, and dust. Most of the Golds gone now. They used to get a Ounce a day.
A good panner will get a ounce a week in the best places. No real nuggets at all there.

Funny story, a friend & I went there once, I had pan and sluce and such. The big joke was that he was going to find Gold before I did. (He was going there to hunt possums instead)
I'm setting up my sluce just after we get there and he says "Found it, there's some Gold"
And I'm like "WHAT! Already?"

"Yeah, just right there" and points.... At a broken cellphone in the middle of the stream....
Yeah, that's Gold. And I gotta admit it too.

But... Here's a YouTube of a small shaker table. https://youtu.be/tP2_l7SnyVo
The reason why I made this post.

The conversion would be 300 / 31.1 = 9.64 troy ounces

The table in the youtube video does work but the mechanics use a connecting rod on a eccentric to give the table reciprocating motion. Water passing over the table does 90% of the work.

A Wilfley table not only move back and forth with reciprocating motion but has a bumping motion on the return of the table, prospectors panning for gold will often bump one side of their pan with the palm of the hand to bring out the fine gold the Wilfley table mimics this effect.

On the Wilfley table you can adjust the bump from a light tap to a much more aggressive one, heavy gold only requires light bumping while recovery of the lighter flour gold requires a more aggressive bump to move the flour forward.

In this video you can hear the bumping action, this bumping action also encourages the heavies like gold and platinum to settle deep into the riffles to where they work their way towards the end of the table to be collected as concentrates.

IMHO the Wilfley wins hands down.

Do you know where I can find info on building an air separation table? or how well does a centrifuge work? I have a granulator geared up.. but thats as far as I got. I tried to make a small mock up for an air table but couldn't get it to work.

I think the shaker aka ( Wilfley ) table would be best suited to separating the plastic from the copper chops.

If you prefer a turn key table try Savona Equipment in BC, they have new and used tables.

I would also do some research on spiral concentrators, it is a type of centrifuge that I believe is capable of processing more pounds per hour than the shaker table.

If you have deep pockets the Eddy Current separator would be the Cadillac for separating PVC from your non ferrous. You would end up with a dry product. I did research this type of material separation conveyor, they're not rocket science anyone could build one.

I have been looking hard at these tables.
Part of what I am saving up is silicon chips, flatpacks, thru hole, plug ins and the 'j' legged eproms for incineration and the Gold/Copper leg recovery. Also the power transistors which I find out have Gold wire connections too.
Since I have a lot of this saved up, and returns seem to be about 0.6-0.7gms per Lb.
I have a good amount of Gold there.... Ounce plus... :-)

And since I have about 200kg of plastic coated Copper wire, selling or burning is my only option, till the shaker table and a homebuilt chopper would give me the chance to get #2 price with a clean process and over 99% recovery of Copper.
My yard only pays the lowest return % for plastic coated wire.
And 50kg of my wire is the 4 x2 strand telephone wire with no outer cover = 85% return...

My quick question is, are the riffles tapered in height towards the end?
I am thinking that 'baby corrugated iron' could be used as the riffle board if its not nessesary to taper them.
Everything else seems pretty easy, I have lots of time to build one, its a investment in that time too.

A couple of days ago my neighbours son popped over to ask me about 'making a home built casting furnace' for melting Ali.
He had a mid 70's book with some rough details in it.
I pointed out some stuff for him, like we cannot get the cement here, crucibles are far too expensive here and his size ideas a bit too small.
And it will not melt Cast Iron..
But, I dragged out a diesel furnace burner/blower I have, showed him some gas bottles for casting in, mentioned using kittylitter & sand & cement, along with some refractory insulation as cement and recycling cast Ali as Ali for casting.

So I think we could make one between us. And I can use it to incinerate silicon chips....
He can do the actual physical work and I supply parts and ideas, nice deal.

I gotta say alloy2, without the shaker table idea, it'd be a used gas bottle as curcible on gas hob and Gold pan the wires out....by hand.

Using a shaker table would be perfect for Gold mining in our areas too, there's no 'claims' for hobby panning/mining here, just free areas to do it in and a 'environmental' guide to follow.

Hobby mining is about a Ounce a week and less...per person. NZ$1300 a Oz?

Here is a good video of a homebuilt one that appears to work good. Not really a shaker or an air table and most sorts before his centrifugal seperator but appears like a good wet setup.

Nice set up the guy who built it has a good grasp on gravity separation, he's using a sluice to separate to copper from the plastic. The heavier copper collecting in the riffles with the water carrying off the lighter plastic.

If I were only running copper chops or coarse gold over the table would use none tapered riffles then for fine gold tapered.

I would avoid using iron crucibles, molten aluminum becomes a solvent when molten and will pick up impurity’s from the iron creating an unknown alloy which may make any castings you make brittle.

Here's the second video that shows up after the first on at separating system and is really explained. Mike

This is for my Kiwi friend in NZ. my buddy manufactured centrifuges for recovering placer gold then after his passing I acquired all of his drawings ranging in size from 12 to 38 inches. The one shown below is a 12 inch unit that is capable of processing 160 pounds of material per minute.

I hired a fellow from the RFQ site to convert the paper drawings into machine readable language so that I may have the parts cut out using a laser CNC for neat accurate cuts. I would recommend this site that offers CAD, and all sorts of CNC cutting and machining, RFQWork.com- Online Job Quotes for Machine Shops, Fabricators, Molders, Stampers, Casters Forgers and more!

The RFQ site has a membership that will do short runs and prototyping as well larger contracts.

I'm building a 12 inch centrifuge very similar to the one below with the exception the unit is powered by a gasoline engine from a riding lawnmower with a vertical crankshaft also using the gasoline engine makes it totally portable.

Cool picture of some local quartz, wet with water gives it an electrifying ghosting effect.

Correction the mercury was lost by previous prospectors.

Not going to get into a flow blown story on how this discovery came to be, those of you that also belong to the GRF can get the full scoop.

What your looking at it a rock that I split on the fissure line, the surface wetted to enhance the image, using a tungsten flash took this picture. The silver material with the purple halo is a mercury / gold amalgam.

The rock once pulverised and ground into mud when panned had plenty of visible fine gold that the liberated mercury soon stole from the bottom of the pan. Mother Nature refuses to give up her treasures easy, the gold is not lost just temporarily unavailable.

http://i1207.photobucket.com/albums/...psriuim8yc.png

This is not a nugget, just some gold from inside a fissure.

http://i1207.photobucket.com/albums/...psosticyxy.jpg

Specimens such as this arsenopyrite have been known to contain some serious amounts of gold. The problem is that the gold is locked up in arsenic and that the ore must first be crushed then roasted to recover the gold.

The specimen below weighs over 5 lbs.

All I wanted was a 2kg bar of gold to call my own instead gawd with his sense of hunoir gives me a mountain of platinum.

This is a continuation of my past summer project at the waah plant. I have isolated the source of the platinum to two different sources.

That black sand at the wash plant contains a cosiderable amount of platinum but the mother load is in the rock of the out crop located at the pit.

The rock samples taken from the outcrop initially look black but after pulverising are really green in color.

The pulverised rock has visible inclusions of platinum along with some sort of sulphide mineral insoluble in both HCL and AR none magnetic to boot.

New learning curve coming up on sulphide minerals.

But the constant use of grey matter keeps it interesting.

Use of smartphone makes it difficult to post pictures. If you look at some of my back posts there are pictures of the wash plant and out crop.

The outcrop is the source of the platinum found at the wash pit.

We do not have a core drill but have the equipment nessesary to drill blast holes. So were going to blast some rock to get at some fresh un weathered rock.

Prospecting has been thus far full of surprises the platinum in the outcrop has a chemical symbol pts II, it's a black sulphide.

Had it not been for the use of chemistry the platinum sulphide would have been discarded as a black mystery tossed and forgotten.

A fortune lost to ignorance.

I bid you all farewell wishing both friend and foe good fortune.

Thanks for your contributions. I look forward to you updating us on your progress. I love reading of your successes but I really respect you for sharing your failures(or pre-successes might be the correct term).

73, Mike
