Re: Followup on "The Cube"

Hello there Trev, I thought NZ had dropped off the edge of the earth :smile:
I thought you were still dredging all this time? Glad to see you are back again though.
Keep posting!
My son is still in Nome. Do you still have his email?

Re: Followup on "The Cube"

Good to see you back on the board Joe.

Looks like a good idea, but I wonder about excess water flow to the cube also. We hear it a lot but most don't pay any attention to these words. Classify, classify, classify. I believe that you must run same size material at once. That's why the topper has a 3/16" hole size screen. The cube is not designed to be a dredge, run and capture large nuggets, pickers, flakes and flour all at once and it has to be kept clean as the mat fills.

JMHO for what it;s worth.

Hi Trev,

I very much appreciated the history of the boil box and gold cube and your explanation of the operating principles that you gave us.

Re: Followup on "The Cube"

Hi All

Lip. No I dont have Arlies email. If you do I would appreciate if you could send it to me. My email is kiwigold@hotmail.com.
And now back to the Cube. Joe you get 100 outa 100. Yep a hydraulic elevator also known as a blow up. And let me tell you, it leaves a power jet or suction nozzle for dead. The secret is getting the throat and jet in the right proportions and I seem to have mastered that. Mind you it took a lot of math equations. And math is not and never has been my favourite subject. But I got there. As to rock lock ups. It has a hole at the top with a screw plug. So its just like a power jet. Use the ram rod. The prototype is built out of PVC plastic spouting pipe. How long will it last, who knows. The wear points will be on the bends. But as I am a plastic welder I can reinforce those by welding a plastic plate on, just heat , mold and then weld.

And I knew you guys would question excess water flow.
I even had Mike Pung jumping outa his pants when he saw a video I posted of me overloading the cube in a test run, with excess water. And boy did I overload it. But lets get into hydraulics again. What controls the speed of the water is the angle of the individual trays. Much like the angle of a simple sluice box. The higher the angle the faster the water. Right.. And now we take into account the slats that protrude into the boil box. They control the water flow, no matter how much water you chuck at it. The flood gates (slates) will only allow so much water through them.

So what happens is, the excess water back pressures up on the tray above the boil box. Not far enough to remove gold, as we all know the majority of the gold is caught in the area just below the boil box feed area. And lets face it, the top tray gets the majority of the gold, a little on the second, and virtually none gets to the bottom tray. And beleive it or not, the more water, the more back pressure, well it makes a higher column, and that actually makes the whole system even more efficent. So excess water only creates more depth, but the speed of that water remains the same. So the gold retaining capabilties of the mats are not effected.

And I speak with some knowledge here, after all I was the one that started this grand affair. Man we pushed that beach table 8 cubic yards of straight heavy black sand an hour, and I had to throw the water at it to keep the slurry in suspension. The more we back pressured, the higher the column and that is why I achieved a 99 per cent catch rate.

Many think that to catch fine gold you need a low angle and a minimal water flow. Actually its the opposite, a high angle and heaps of bloody water.

But to appease those who may disagree with me. Well its a pretty simple fix. On the Cube Grizzly and tray, I can block of the water supply ( to suit) by blanking the drop down area, so if needed I can regulate the water supply, but still get all my three eigths minus going through the Cube system with the amount of water that still achieves efficentcy. ( Just to keep Mike happy)

Now back to the hydraulic elevator. I know a guy who could take that idea and produce a commercial product. A one piece plastic moulded wonder weapon. And his name just mite be Mike Pung. He is not only a brilliant wood turner craftsman. He has foresight and the balls to run with things. Look what he has done with the Cube.
Perhaps someone here mite just give Mike a heads up and tell him to contact me, and he may have a new project and product.

I have another pic somewhere where I fabed the blow up into a wee dredge set up. Now lets go look and photo bucket it. Like all things with energy, there are no free lunchs, the elevator is governed by the same rules. The higher you lift, the less you can go down.

My system is designed to work dry banks for flood gold. I only want the top two feet. Hence the added water supply via a 1.25HP two stroke motor with a small trash pump. And if I work below the cube I will have ample water, as the elevator will supply that. I am at the moment running the elevator on a 5hp Honda with a P180, running at just over half throttle. I have today ordered a P90 Keene Pump coupled to a Honda 4stroke 2.5HP and will give that a try out to run the elevator. I ike light thngs, buggar I am 66 years old now. I just want to sit there on my little garden plastic stall, sucking up heaps of flood gold and get rich.

Well thats the plan anyway.

And yep Chicken Miner, havent forgotten you.

So more to come.

Joe will get back to you via PM. Yep I met Eric. Damm nice guy.

And that Canadian site is the bzzzzz. I just got a new puta a day or two ago, so lost all my bookmarks for gold forums. So thanks Joe.

Cheers Trev From very well down under in NZ. The jewell of the Pacific. ( Well in summer anyway)

Cheers Trev

Re: Followup on "The Cube"

Hi All

A few pics of days gone by and the birth place of " The Cube"

Enjoy. The gold picture is some old cons that I had amalgamated. They were sitting in an old rubbish bin for five years. I just never got around to biffing them out. So just for fun run them through the Cube. Well buggar me days, got about a gram and a half. The cube caught some mercury that had escaped me. So I retorted it and got a few blobs of baby pu also. Bloody ugly gold. no wonder it wouldnt amalgamate. Tarnished and rusty.

The beach table is an upmarket version of mine. Pretty cool eh. A bloody giant cube I call it. Its now working my old claim I sold many years back. I wish them well. Poor buggars I got most of the gold. They are the third owners, and its a beach that does not replenish. Rite off to photobucket once again.

And some old pics of my black sanding days. The Mk1 beach table and the Mk 2. A bloody plumbers nitemare, valves, pumps and hoses everywhere. But it was fun and made some bucks. The wee girl in the pram is my daughter Vanessa. She is 26 now and a chartered accountant. Currently in Norway with her partner, who is also a Chartered Accountant, working for KPMG the world wide accounting firm. Comes back to NZ in two years. Well she didnt get her math of me that is for sure. But my Dad was brilliant at math, I just didnt inherit it. Bugga.

And the pic of the gold dredge fab. I can cut one bend out. I was just fabing it with a bit of plastic spouting down pipe, as that is a cheap option of extending your suction hose. Cunning eh. Suction hose is dear to buy, plastic spouting pipe, very cheap.

Rite photo time in no particular order

Re: Followup on "The Cube"

Hi All

Just doing a wee bit of thread stealing, damm Fast Eddies was in Tok. And I got to Circle. See I have been there.
Just gotta share the Buffalo pics and what happens if you accidentally hit one in your vehicle. And then its back to the Cube, and the good stuff, like gold stuff.







Lester Cobb (RIP). Up that remote valley. What a fine man. Stayed on his airstrip for five days. Evening dinner at his place every night. And he even came down to NZ to do a bit of hunting, that was before I met him. Talk about a great bloke, he was it. Yep Indy Eric was there with his son and you know who



Oops some dead Canadian Buffalo, a bit sad. But what hit them.



This the nite before. He survived with minimal injuries. Thank god for airbags. But it was a straight piece of road for miles.



The guy at the Roadhouse told us all about it. The wreck was towed to his place. Man it was in the wop wops, miles from anywhere.

And so now its back to gold. But see I did get to AK

Cheers Trev

Trev, your old school clean-up tool is most likely dumping thousands of colors overtheedge (now I know the meaning)
You did need the cube! Looks like the cube works up to a certain amount of gold but I am a homemade kind of guy. This is my style http://www.youtube.com/watch?v=_dscwhK5-lY and yah it's me with only 10,000 views for 2 years.....

Re: Followup on "The Cube"

Thanks for the link to your video. This last year I used the Cube to do my clean up after running the material through a 12 mesh classifier. As mentioned by Dick, I too had a couple of flakes make it down to the last stack but only a couple. I was very pleased by the fine gold it captured. I don't run near the material some folks do and so I cleaned up my gold by classifying it (and using a magnet) and then panning and re panning it until satisfied I had most the gold, right down to 100 mesh. Then I dry it in a Teflon pan (works great), and then I place the gold on paper and lightly blow over it. After a summer of this you get pretty good.....

Re: Followup on "The Cube"



This is clean-up using a sawed off and narrowed pop and son. Been using them for a longtime in a bigger version till it dawned on me to make em smaller and save some panning time.I have one, one third the size of this one but I have only used it on coarse gold so far.

More than half the gold is minus 20 mesh with maybe somewhere between 1/2 ounce to an ounce of minus 70 mesh. The loss isn't fine gold but odd bent flakes which you can grab in the tailings if your lucky. This one leaves about 12 fluid oz's of cons to clean up.Somewhere around 18 ozs there but I still ain 't finished cleaning it. It was supposed to be more than that in my mind. It's from a new dredge that I didn't calculate front and back ratio due to laziness...

Re: Followup on "The Cube"

For your consideration... I got one of these from California Sluice to use as a gold cube " feeder "...

I use a hopper to gravity feed material into the top of the header box.
The hopper sits in the header box with an adjustable gap between the bottom of the hopper and the surface of the header box (usually set at 1/8-1/4).

As the process water flushes material away from the gap area, more material drops into the gap area, working as a continuous regulated flow.

The width at the discharge slot is just right to drop into the top Gold Cube, and it has a couple of drop riffles built into it...

After reading this thread , I am thinking about getting a second one of these, lining it with GoldHog mat , and mounting it at the discharge of the Gold Cube to ensure capture of the "bigger stuff" ... (The Gold Cube does a great job of catching the small stuff...)

Re: Followup on "The Cube"

Well, the Cube was not designed for the "big" stuff. And, I think if you start feeding it with "big" stuff, you will lose the function of the Cube. I.E., lose the ability to retain the fine gold.
You might as well take out the matting and put in your Gold Hog mat.

Re: Followup on "The Cube"

N2au,

I use my expanded metal sluice,Pop and Son sluice,California sluice,Gold grabber sluice or whatever one wants to name it sluice to feed the stream where the gold was taken my blacksand. Why would one want to keep more blacksand by feeding a cube with one these?

It does look like one could use just a portion ( a side of the cube) to remove more blacksand.

Remember no matter how small gold gets it is still 15 to 18 times the weight of an equal mass of water.

I have a few oz's of -100 mesh gold I am quite sure I could catch 95% it within the first 4 inches of the above pictured sluice....

The only reason the gold is so far down the above pictured sluice is due to the amount of gold.

By the way the gold came from about 600 yds of ground not anywhere close to a road.

Re: Followup on "The Cube"

Hoppin'

Harry is very right, a 'Cube is only a well designed concentrate concentrator. It was designed and developed specifically toward recovering very small, already recovered, in some other device, Arkansas River (or other location) Gold. By extension, it was also directed towards ANY very fine, previously run, Gold, from any type concentrates.

It was designed to retain (at the specific expense of similarly sized Black Sand), the small (- 1/8" ) and very small sized Gold from already run concentrates. Just think of it as a finisher - prior to absolutely final cleanup.

Re: Followup on "The Cube"

Joe,

I understand what the cube does. It is also has a highbanker version... Mine does too!

I am just pointing out that a quite crude looking sluice slapped together in a half hour or so can do the same thing.

Whether one catches gold the other will not remains to be proven in my eyes.

Joe...
Well I have to disagree here. I think the Cube was designed to PASS -1/8" stuff, not retain it. The "vortex" mat is the weak point here.

I am thrilled with the Cube because the majority of my gold is -20 mesh. The Cube shines here.

After a season using the Cube on cleanups, I now know its limitations on MY concentrates. I won't run anything +18 mesh through it because I know I have greater than 30% chance of losing it.

Re: Followup on "The Cube"

Oh Jeez Dick!

I mis-spoke, Iím sorry.

I was trying to say that the 'Cube was originally conceived, developed toward and shines at recovering Gold (OK, Platinum, too) from minus 8 concentrates.

Before I bought mine, I spoke with Red on the phone (at great length) about it's concept and directed development. What a cool guy! The original, original, original intent was to create an Arkansas River Tiny Gold getter - and it has been a great success.

The "High Banker attachment" was, it would seem, driven by customer interest in a 'one stop shopping' bank run modification to the original 'Cube design. To my thinking, ditching any Gold over #8 is just wrong for the areas where I work - but for certain circumstances, in other locations, it could be a really great deal.

I surely didn't mean to suggest that the 'Cube should try to, somehow, retain black sands - after all, I want to find Gold, not black sand!

Thanks for keeping me on the straight and narrow!

Joe

Re: Followup on "The Cube"

Joe,

I did say that it looks like it works and that if a guy isn't getting much color he could reduce the amount of blacksand by just using a few inches on the side of the the cube.

But for my style of mining in the boonies it does not suit my needs better than what I am using.

It for one fits into a backpack about as easy as does a spiral wheel.

Number two it requires a battery so that means I also need a solar panel or a generator which is more weight I have to deal with.

Number three I cannot place it in a creek or my dredge where I normally clean up.

Number four is that it is expensive.

Number six is that Dakota Fred whom doesn't know what he is doing other than making very expensive mistakes endorses the thing.

If a guy wants to be prudent yet is worried about losing gold as most people do when they first get into this game is just buy some 1/2" expanded metal.Make your sluice however long you want that makes you feel confident about your recovery then test your carpet by dipping sections into a pan. You can then downsize your sluice to a point that is acceptable to you in terms of quantity of blacksand and recovery.

Re: Followup on "The Cube"



Here is a another pic of the same clean up showing the back of the sluice. No screening was used other than the one inch grizzly in my dredge. In this case I was being more careful than usual because my tailings were going into the creek. I had to scoot some pebbles through.

Granted this particular spot is not super fine gold I have found through the years in other places that this simple sluice works there also.

Re: Followup on "The Cube"

I think the Cube would be a very good gold getter. I've looked at it for a while and watched the tests that others do.
I have a number of sluices. Le Traps, home designs, drop sluices, magnetic sluices, (the magnetics are easy to pack, just fling 'em at the truck and they stick) etc. The P/S sluices are the best so far. They will catch the very fine gold that is the majority of what I run into, as well as the chunkier stuff.
The drawback is that you get a lot of cons the way I run them. So I classify and rerun the cons while checking for losses and I rarely find any losses.
A few years ago, I setup 4 Le Traps in parallel to get a higher volume of material processed. The incoming material was classified and sent to a plastic animal feed trough with 4 outlets to feed the Le Traps. I was unable to spend enough time to polish this system and I shelved it. I was able to get 2 L/Ts working, but the classifying was the problem.
I may dust this off and use this for the gold down to say, -40 and add an additional classifier downstream to size and direct the smaller material to an cascaded P/S setup.
By doing this, I eliminate mucho mass and can optimize the L/T mesh size. Since the L/Ts are really good at catching both the coarse and fines and the P/S at catching the super fines, read -100 to -250 or so, this achieves the goals of relative simplicity, super recovery and easy portability. This modular model is adaptable to small and medium needs.
Classification between the stages is the key, followed up by optimal recovery for that sized material.

Re: Followup on "The Cube"

Dick, did you get the 3 or 4 stack? I got the 4 stack and for next year I am looking at using hog mat on the 4th stack. It will catch more black sand in the 4th stack but should catch the couple of bigger flakes that get through once in a while and the 4th stack would be easy to pan as at that point we are looking for the bigger flakes.

Re: Followup on "The Cube"

Kurt,
I have the 4 stack.
Yes, replacing the mat in one tray seems like a good option to me as long as the mat choice will work with the amount of available water.
Your correct, since all we would be looking for is the larger stuff it could be screened off with minimal unwanted material to contend with.

Yes, the mat choice will be the deciding factor. I think I may try the medium velocity mat by gold hog. Right now just thinking about it.

You folks up at Chicken have had some serious cold up your way. Makes us folks in Wisconsin look like we have a heat wave....
