Gold Hog is at it again......

Check this out...... Looks like something that might just work.... Of course I am a fan of fluid bed recovery methods.

Here are some early attempts at what gold hog has done a pretty good job of refining.
I think the biggest improvement is the addition of the classifying tube, while the E-Tower and Quicksand work you will quickly see where they were losing a good bit of gold.

Osterberg?s E-tower gold recovery

And of course the Quicksand gold concentrator.

Well lots of views but no comments?....
Has anybody tried one of these yet?
Anyone thinking of trying to build one themselves? The concept is actually quite simple once you sit and think about it.
I am an advocate of fluid bed concepts ..... You just have to understand what is really going on in the bed and how the shape of the gold actually has more to do with the end results than the weight of the gold.

I do think 300 bucks is a little high for this thing but I also understand they have to recoup development costs and manufacturing costs.
I know what it takes to be in business since I am a business owner myself.

Doc introduced the Gold Cyclone back around Feb/March of last year as a forum topic on his prospecting forum of which I am a member. There are numerous questions and promises to purchase but no user reports that I recall. This may be because the users/buyers are not members but I suspect probably because of poor sales.

I love the science based principles in the design and I am convinced it works as advertised. One downside is that the material still has to be screened after each step. If I had or was producing more than than a hobbyist amount of cons I would seriously consider getting one. It would be interesting to see how well it would work with beach cons. Doc says he has tested down to about 150 mesh but that is probably the upper level of average gold size on your beaches. In the demo, Doc says the smaller the gold the larger the amount of Hyd. Eqv. black sand, etc. there will be but if there is a significant reduction of them it would certainly ease the final recovery effort especially if, at that tiny size, it makes the cons easier to pan as it does the larger sizes. I would like to see testing results based exclusively on minus 100 mesh beach black sand concentrates.

I can see where it is feasible to build one and it may work ok. I think the water supply is necked down by a nozzle or some type of reducer to create a venturi effect and speed the water for the vortex action. The 200 mesh screen seems to be, mostly, to support the material at or just below where the vortex water is introduced as well as to prevent some migration of material through it. Or it may be part of the nozzle. If some does pass the screen it should pass back through during cleanout.

I haven't been around in quite a while so I missed Doc's post regarding the cyclone... sorry about the redundancy, I will look up Docs posts from the past, Thank's for the heads up...

I agree it should not be too difficult to build one if ya wanted to.. the function is in the science of particle size and vortex or hydraulic support of the particle size.
I would like to see the results of beach gold recovery/cons reduction as well.
