Here are a couple of videos of another concept for recovery gold. The idea is that you can run all day or weekend before a clean out as the gold will stay in the bottom of the drum until you’re ready to do a final clean out. Obviously running wet is better. Much smaller version using the drum wet or dry. Anyone interested in building the Drum its based on a mixer sold by Home Depot. The front cone is removed and the paddles inside are removed. Then a 14" or 16" trommel basket is installed with the back of the basket raised off of the back of the mixer. Then a 3/4" or 1" ring is installed on the front edge of the large drum to retain the heavies. Link to the cement mixer at Home Depot. Any quality steel shop would have the means to cut the 1" ring to the diameter of the front edge of the drum as well as rolling the expanded metal or get a pipe and start drilling holes. If you need a drill pattern contact me as I got the pattern to center punch and drill the holes and have evenly spaced holes. http://www.homedepot.com/p/Proforce-1-2-HP-Portable-Cement-Mixer-105890DPT/202081851?N=5yc1vZc7qb Rather cheap way to have a gold recovery machine running wet or dry... You would have to have a small generator of maybe 1500 watts as the motor is only a 1/2 hp of which generally pulls on the high end of 8.5 amps. If your running wet you would want to place a GFIC outlet between the generator and motor. I have never seen one in use but it does look interesting.

Below is a link to my new unit that's taken ages to perfect, will change the way dry prospecting is done for ever . Link :- http://golddetecting.4umer.net/t19885-introducing-the-gold-churn jack .

I've been working on a simple hand operated unit that can concentrate down dry material quickly, no need to classify just feed in the rocks as well . Have made a prototype that works at last after previous fail designs , this one is very portable for one man operation . My question is who do I offer the design to as I'm not going to go through any long patent BS . Would Garret be interested as an example ? Regards Jack

Hey Steve, Did you ever get a chance to use the rocker? I am curious about the its efficiency on fine, flat gold. Also, what does it weigh?

Got a few questions here. First I have a small impact mill that takes 3/4 minus material and will crush it to 100 mesh or smaller. I am looking for something that will take 2 or 3 inch material down to 100 mesh and not break the bank. I am looking for a gas powered unit that can be run on site. I am running desert material so all of my rock is dry. I fill buckets and take the material to Oregon. I crush it then run it through a concrete mixer with just a trickle of water and some Simple Green. Then I run the concentrates through a Gold Genie which recovers a large majority of the gold. The problem is I am left with a lot of rock that is oversized, most in the 1 inch to 2 inch range. My material is coming from a pit next to Rick Watkin's first pit in Nevada. Or maybe there is a more economical way to go about this or even with fewer pieces of equipment? Any other ideas? Thank you!! Steve

Besides all the beer drinking & playing up I like to make stuff , last year I wanted a hand operated thing that would concentrate down the heavies quick so I could do less panning . First photo is the proto type - Then I fixed up the bugs & changed angles plus fitted an hand mixer on the next model . Works Like this , throw a bucket of water in then the same of material , rock back & forth whilst using the blue handle to stir the stuff up so the heavies drop quick into the bottom trap . After a minute stop and collect the stuff from the trap by undoing the 2 clamps , empty & start again . When you get a bucket full of the heavies run that through so you only have one pan to do I called it the gold pram . Jack .
