Murilo's Gold

Post by docfeelsgood »

Hi Murilo ;

Awhile back you mentioned you like caves and mines . I think a long time ago you said you or your family held some patents on a gold concentrating centrifuge ??
my question is do you have any pictures or drawings of this machine that you could share ?? is the machine still being manufactured ?? how big was the concentrating bowl ?? At what efficiency did it normally operate at ?? How much material could it process per hour ??

Thank You .

Regards , "Doc."

Hey Doc!

I think you just gave me an idea!

To my knowledge no one has found a use for Milkovic's pendulum machine. I think it would make one hell of a "Specific Gravity Classifier". if it could not bust it up it would surely shake the s--t out of things.

Hi, Doc!
Very nice to know about your interest! Really! :)
I don't remember when I said about this.
We have in hand a prodigious equipment... if you know this market, you'll know why we couln't come in truely in it.

There are much to say, specially after to know the application you have, but in below I'll send some high lights:

- I use to say we have a ''process'', the equipment is a tool. This process is exclusively for the capture of FREE, or liberated, gold particules and it is not a copy of any other you may know.

- we have still 2 used equipments, one in very perfect conditions. A friend of us intent to buy at least one of them, in 2009.

- the concentration is by gravity and is very interesting, because inside it kept an ''artificial part'' of the machine, which is ''the own body of the concentrated'', that acts as a kind of trap. The volume of concentrate will not be increased, but all sterile particules are are under constant change while continuous fed.

- the concentrate is kept augmented thanks to water and movement, and exactly EVERYTHING, before ejected, will sunk in that concentrate, almost a kind of sponge. Even water will sunk over its top.

- one can say it's near to be a authomatic pan, with 1,2meter diameter, but it works with continuous feed of pulp ( water + ore ), for up to a week, if you want. Don't mind duty water, mud, heavy sterelies.

-the coloidal behavior of pure gold is around 5 microns, 0,005mm, but literature fixed in #180 the limits for gravity/mechanic capture means. Our process capture economically gold under #400 or some 0,036mm. We just don't know exactly its limits, but in practice, with natural Au, we can garanty around 95% of the Au. ( to be sure, I must know well your application before to fix this rate, ok? )

- it can also be used as pre-concentrator, concentrating sulfides 4,2g/cc, or if needed many parallel with discharges to a series equipment. Once I have seen our machine working and concentrating Au with a concetrate that resulted in more than 22kg of Au in grains. This feeding was coming through a by-pass from the flotation, before to a cyanide complex. (it's not good for diamonds.)

- the equipment weights 1,1ton, expend from 2 to 3 m³ of water per hour, and will receive solids from 2 to 4 m³/h, deppending upon mineral and working phylosophy. The power is of 2HP, triphasic, 220/380/440V CA. It will work the best and free with fine milled ore, under 1mm.

- the discharged may be decided and commanded, by hand or authomatically, in cycles:1 hour/12 hours/ 1 day/ one week... as wished.

- it offers, here come the reason of the extraordinary results, three main linear factors of controll: turns per hour, inclination in degrees and volume of water. If you see it working, you'll see that it ''respects'' to the material, without any apparent rush.

I have many photos that I may scan and send in pvt, due to weight.
The ideal challenge to me would be a contest for a pulp that would be cyanaded, ''due to its too fine Au grains''.

If necessary, we can design it for cheap fixed to ground application and bigger for higher volumes, where is to be expected much better performances of volumes and capture. :)

There are other applications for it.

Pls, send me details, if possible.
Thanks and best regards.

Murilo ;

That looks like a very serious machine and very well constructed !!! I dont think an old cripple like me could keep up feeding it .

somewhere around here i have a picture of a small compact separator that i have looked for for many years . i will try and find it and post it .

thank you very much for posting this information .

regards , "Doc."

Doc, hi!
My equipment is what can be called ''professional'', but this will not exclude any old cripple... if you are seatted over the real ore... :)
A small hammer mill, a good ore and 1m³/h in my concentrator may be the solution to a lot of troubles.
You may use to feed that mill using a small blower/vacum set.
Too popular and simple ways will lose, easily, up to 95% of that precious yellow metal.
Except if you only want to play and if you deal with great grains of secondary or tertiary gold, very common in the US, you still can make a good money.
BTW, I never trust in centrifugues, that are to much violent to any shy gold.
Can you talk about the mine you have? I'm curious... you know minners!
If I can be helpfull, just call!
Best wishes!
Murilo

Jim Mich;

most of the gold i ever recovered was dug with a P&H shovel ---- that's with a pine handle and a 2 1/2 foot hickory boom !!

tangible gold is much more valuable when earned this way as compared to some certificate like you have tacked to the wall .

you might notice that after running your P&h all day that your beans for supper will taste a whole lot better than they did for breakfast !!! and if you prefer warmed beans you could i suppose start a fire using the certificates , thats all they are good for anyhow !!!

Hi Murilo ;

Of course i am not angry at you . quite the opposite .
That bewhiskered old savant decided to rain on my parade so i just threw a rock right back at him !!! perhaps i will call him "Rainman" !!!

we here in Arizona are limited by two things , government regulations and lack of water !! the "bureau of land management" [blm] which controls a large portion of the state has now stipulated that you can no longer just take off across the desert . if there is not an established road or trail to where you want to go then you must walk or go horseback . no motor vehicles off the trail !!! i understand they are going to shut off the use of those trails by motor vehicles shortly also . this area was heavily mined years ago and there are many mineshafts , a lot of gold was produced . in some instances they will issue you a temporary permit but the equipment you are allowed to use is limited to 5 Hp. or less !!! any test holes you dig must be filled in again also . much of the best prospecting areas are now owned by the military , yuma proving ground , and the barry m goldwater bombing range . they control many thousands of acres . other productive areas have been turned into parks and wilderness areas , if they catch you putting one worthless pebble in your pocket the fine is heavy !! they have raised the price of claims permits so high that most people have let them expire , once they expire they are gone for good !!!!!!
due to the lack of water about the only thing that functions is drywashers . i do have one small vibratory concentrator with small gas engine that removes the large cob and i take the fines out to water for final separation . you can also forget about using mercury anymore around here !! perhaps i will post some pictures of equipment this wk. end . i have done some prospecting in north carolina and georgia years ago with what i call minimal success . some days its beans ,, some days its steak !!!! at least i ate and that is all thats important !!!

there are still two hard rock mines operating nearby that have been there forever . they use cyanide process and can hardly breathe for the government controlls .
i understand colorado has basically shut down the miners due to the discovery of a few dinosauer bones !!! perhaps Scott can elaborate ???

Best Regards , "Doc."

Hey, Doc,
you are in trouble! I'm sorry.
Why not join to enemies and start to find those dino bones?
With the experience and the nose you have... :]
You can send names to them... think of this!
If I had more data about the ore you have, maybe I could find some way, for free, of sure.
Take care!
Murilo
