Nevada Desert Sluice (The Oldtimers Would Have loved this!)

Nevada Desert Sluice

Desert Sluice

This aluminium and stainless machine collects the gold fines 98% in the miners mat under the ali grid.
It sorts the shovelled dirt into lumps at back, medium sizing (max detectable size) in a bucked underneath, and fines run through the sluice.
Water needed to run 40 ltrs and uses 20 ltrs water in evaporation per day.
Basically if we carry 5x20 ltr containers in the cruiser we can stay bush for 6 days
Small 2 stroke runs beautifully starts every time and stays on idle.
This can be used with damp dirt and the unit can be disassembled easily and carried by one person.
Designed to do 3 ton + plus per hour.
Easily keeps up with two guys on the shovel
The two separate piles lumps and medium size materials are detected as you go along.
Easy operation and solid built.
It is being used on a regular basis in the wa goldfields as said the little vid was made soon after it had been on it's first trip , I always look after my gear
One point the desert sluice is basically designed for the hot dry summers and where soils are usually very dry
Ie an alternative to the dryblower
It screens the shovel intake dry and that falls to a pile at back
The material then falls to the second screen still dry and the + 2.5 approximate falls dry to a trough under the machine
These first two dry piles are detected as they grow
The -2.5 dry material then falls to the internal hopper and is fed to the top/ back of the final screen/ sluice it is sprayed( found it just needs a gentle regular flow) and the fines easily work their way down the sluice grill with the miners mat underneath
If there is a build up the water vol are increased an the hard bristle Broom is used to work the fines up or down
The desert sluice was made to recover the fine gold only and as such the fines are usually the far smaller
portion of a shovel load
In wa have approximate 65% of a shovel load is fines silica and magnetite/ iron oxide
So in this case we find the clowdy water settles quickly, and when we work limestone areas and decomposed calcretes Ther are far less fines
Water usage really is good naturally with care
One could use three troughs if need be, to rotate if the 55 liter black trough is filling up to fast
We have found it doesn't need this and it would need more water in the circuit
This machine is easy and a gem to use and this choice of pump was spot on
I will attempt to respond to anyone that has questions

Looks tough as nails. Good work! It will do the job for YEARS! Tnx TTC

 

[ahaulil]

Looks nice, but has it ever been used in the Nevada desert?

 

[arizonaames]

It would plug up in a minute with the clay soil conditions of the northern Nevada deserts like the Black Rock Desert next to Rabbit Hole. Even Panning can be a problem when the water turns to pure mud. The gold wants to stay in the clay nodules. One has to use a drywasher or a metal detector. This is a recirculating sluice box and will not do the job that a drywasher would do in most situations. To try to pass it off as a drywasher is rediculous. One would need a water truck just to replace the water running in it to run this in clay soils in northern NV deserts or anywhere where there is a high clay content.

Thanks Terry

You picked it right,

WE deal with the worst clays you can imagine aND THIS DESERT SLUICE HAS BEEN DESIGNED TO DEAL WITH HORROR CLAYS.

We change over the larger trough about every half an hour, an the pump has no problems at all.

This country was if I,m correct where the dryblower came from this desert sluice is designed to do the same job.

Rediculous!

Only thing ridiculous is the dude that thinks he is the only guy that works the desert!

We live 9 months a year out back in 42-50 degrees, only dif is the colour of the dust.

No worries mate.

PS, BTW that keene you have is for hobbyists.

You obviously know nothing about equipment and conditions. To begin with, the riffles in a sluice box are the oposite of a drywasher. Clay balls that contain the gold will slide off of a sluice and not be trapped by the rifles unless most of the clay is gold and is heavy enough to be sucked into the opposite riffles. Where will you get your water when you are running your recirculating sluice box? Water in a desert is as rare a commodity as gold. for a month's stay, 100 - 200 gallons is a drop in the bucket for cooking, washing, drinking, and checking your concentrates periodically. Replacement water is 50 to 70 miles away. The clay balls have to be squished and broken up while panning to release the gold that they contain. In northern NV that means rubber gloves unless you want to crack and injure your hands from the alkaloyd, lye, and gypsum that the soil contains. A recirculating sluice is a good tool in some instances but for production in desert condition, a drywasher is a necessity. BTW, a Keene 151 is a multi man drywasher so obviosly you know little about equipment here in the US. Seems your only interest is selling a product and not elaborating on it's usage. LOL

Sounds like a head to head contest is in order.

 

[arizonaames]

No....this fellow's english must be a second language because he posted a recirculating sluice box in a drywashing section. His recirculating sluice needs to be in the sluice box section.

While I am a rookie at prospecting, I have run drywashers in Nevada and Gold Basin, AZ and to call this unit a Nevada Desert Sluice
is kind of interesting.
I would like to play with it at home, but not lug it into the desert.
I hate lugging gas-that is why I don't have a 151. They are beasts and can take whatever two men can throw at it.
Carrying water it no fun ether, I drink most of mine and use very little in the process of prospecting.

I have seen this posting in other forums and I expected to see other people react the same way.

My advice to anyone wanting to push/sell anything via a forum, is to post some encouragement and a little advice to others in other posts.
Gain some goodwill first.

Take your time and build trust and most will accept anything you come up with.
Anybody see the hillbilly rock tumbler used for cleaning coins on YouTube? Looks like heck, but they way the video was presented, I would try it.

Hello Guys,

Theres just one thing , we don't make these machines, or sell them, we are an exploration company, for thirty years now and this was made specifically for our work, in gold, diamond and REE,s exploration.

Has worked exceptionally well in all areas

Just because it wasn't made in the US doesn't mean it is no good! thought the Chinese had taught you this a few years ago!!

Although this machine which has patents pending is a new concept hybrid dry and wet separation.

There is nothing out there as this and just thought some of the less redneck of your lot may have some interest in having new concepts that worked very well, in tough conditions.

My advise to those that are noitalls is don't judge others by your own standards, and expectations, and if you dream of inventing some useful concept and commercialising it, its unlikely you will make any money from it anyway, so don't assume we are that stupid.

Regards Majindi

 

[calisdad]

Well if the Chinese have just one what good are the patents?

 

[majindi]

Oh and to the bright spark that says this should be in the sluice section,

Mate the machine is also a fully blown Dryblower as well with a change over of the tray!

And as it is, if it does two thirds of the processing dry and one third wet that makes it more of a dryblower than a sluice.

If thats the best you can offer, I,d go back to the tools mate.

Majindi

 

[majindi]

Agreed,

We take out patents as a matter of process, more a company policy, we have no interest in commercialising this.

Our serious development is in Direct Reduction of Iron Oxide, the Femelt Reactor, and the development of mining processes.

This has been posted so others can copy for their own use.

It is a dam good machine, quite some work went into getting it right.

Regards Majindi

We don't have any lugging we as all in the bush 4x4 into any area and carry a full workshop and camp including 250 liters of water
This is the support trailer

If we are 'pushing' we use a 17 tone articulated loader so the desert sluice is just a small part of our inventory
The diff is we do this for a living

Before some Wally says it? No.we are not trying to sell the trailer! Iether
