Gold cube and miller table

[bottlecap]

Now that I have a little experience with prospecting I was thinking running material through a gold cube then using a miller table to cleanly extract the cons from the cube might be a good one two punch. Any thoughts? I get really frustrated panning some of the really fine stuff, very hard to separate from the black sand without panning black sand out and probably losing gold.

And how many thousand pieces of that little stuff do you think it takes to make a gram?!?!?!?!?!?

Somewhere in the neighborhood of 200,000......

The guy i use to get the classifiers locally has retired. I went out to his shop and he was selling everything off a few weeks ago...

Hey saw this post after I had already placed an order! Ordered the set with the 30, 50, 70 and 100, paid 50 bucks with free shipping, had to get some though as I am really anxious to see if this increases my gold take, smallest classifier I had was a 12 up to this point.
Hey what is your guys' process for classifying?? I have seen a few people eluding to using several buckets and letting the different sizes pile up before classifying. So say I have a 12, 30, 50, 70 and 100 you would take the material, run it through the 12 into a bucket, take that and run that through a 30 in another bucket then whatever stays on top of the 30 goes into a bucket and so on and so forth? So you are actually collecting the stuff left on top of your screen. Up to this point I have been using the pro pan at the river and classifying down to -12 right at the river then use a combination of my pan and clean up sluice to process in the basement. Still feeling like I'm losing gold and I don't have much to start with here in Mn.

I gotta get one of those magnets.

If your referring to a blacksand magnet there is one pictured and shown how to make it on this site. I made a version of it from "stuff" I had in my shop. it works fine!

Here is another set of screens... Goes clear to 325 mesh... granted they are 5 1/2 in. in diameter but when you get to that point you don't need a bucket sized screen.

Bazooka gold trap co. Also has some small classifiers. They are a little more money, but I bet they are a little higher quality. They come with solid bottom and top tray. Do you really need to go down to 325 mesh? I'm not trying to be a smart a$$, I'm a newbie and am really asking do you need to go that small. I like the small classifiers, I think they would be perfect for bgt. They don't leave you with much cons.

I work beach gold and my cons run through a 100 mesh screen like water.
The whole trick to cleaning up your cons is to get the gold and the duff to be the same size , or close to it......
Like Mike Pung says just clean up according to the golden rule.. If everything in your pan is the same size. Gold rules.

Here is a lik to panning out your cons...... http://www.treasurenet.com/forums/panning-gold/459664-art-gold-panning.html

I've read it before. Good read good videos. I just don't end up with a lot of material in my -100

Then 325 is definitely not for you.
Wish I had that problem.......

Way damn tiny........

So whats going on down your way? anything at whales head?

I use a gold cube....I classify with 8 mesh....run through cube then vial from Miller table

Hey guys sorry I haven't updated you much since my recent purchase of the classifiers. I have used them and like I mentioned I got a 30, 50, 70 and 100. Really time consuming to classify by each size, I like doing it but it takes tons of time. Results have varied greatly, to my surprise I have had most of my gold in the -30to +50 mesh range and also the -100 range but not much in the 50 mesh or 70 mesh buckets, thinking I may start skipping a couple sizes. Right now my process has been using my pro pan at the river, classifying to -12 at the river then bringing everything home for the time consuming crap. One day I tried classifying right down to -30 at the the river but it ended up being too time consuming plus I was afraid I was going to ruin the screen with the larger rocks I was dropping on it.
After tweaking my process a bit I do have a question. When classifying into a 5 gallon bucket when the bucket gets full of water so there is standing water on your screen is it o.k. to dump material in and work it with your hands through the screen? I have been doing that more now and it seems to work o.k. but I hope I am not losing any material that may just be sitting on top of the screen. I would think any of the material small enough to fit through would still go through without the force of dumping water on it.
On a good note yesterday I found two decent little pieces of gold, felt good because I have been going through a bit of a drought, always trying new spots, even driving around a little but still haven't found a spot I feel comfortable driving to and processing a ton of dirt because of past success. Gold seems to be really hit or miss here. You can go to a spot one day and do o.k. then go to the same spot the next day and barely find anything within 1 inch of where you were digging the day before.....really getting annoying! I just want ONE decent spot to rely on!

Nice to read so much about how you are doing. You only need to do the classifying beyond -12 (or even -4) for the last couple cups of heavies...NOT for all your paydirt. (So do this fine classifying at home!!)

Learning what sizes of gold you have is an important part of learning to get gold from your area. Good job there.

Classifying with standing water above the level of the screen is ideal. Much quicker and as you say, the small stuff drops right thru that way! (It doesn't need force of water flow unless you overload the classifier.

How often are you emptying the Pyramid Pro Pan (I gather that is what you are using)? It sounds like you are cleaning pretty often since you apparently end up with a lot of concentrates. You should be able to just continually operate it (add new feed material to it and sluff off the lighter material, bigger stones, etc. AKA production panning) until you have mostly black sands in the rectangular bottom section of the pan below the bottom of the metal riffles before a cleanout is necessary. At that point save everything not just what is in the tube area where the plug is. With production panning you will end up with minimal but richer concentrates to screen and pan at the end of the day.

As far as classifying feed.....I think the Fossicker (inventer) recommends about 1" max size for efficiency so....make it easy on yourself.

Good luck.
