As you can see, it's a fairly simple rig!
It is easy to build, (fairly cheap to build) easy to change the number of filters, to suit your pump's ability/capacity,flow, etc !
You want to keep your flow (gpm), under 6-8 gpm (thru each filter) and a very low, low psi !
"U" !
Don't want to wash any of your gold past or out of, the filter material!
There is a plastic mesh inside the pvc filters, that's, the 3" dia x 18" white PVC tubes.
In both, tops and bottoms,
This plastic mesh holds
the loose carbon from being washed away!
These filters, also, unscrew from the "H", manifold.
That's, so that the gold that's in the carbon material (filter) can be transported to and dumped into the Leach Tank!
I had heard somewhere?
That you didn't want the water to wash over anything metal !
That it might change
the Gold's polarity? and you wouldn't catch much of the gold after it changed polarity?
WHAT'S The HARD PART of all of this
?
That would be
"The Leaching Process"! That's where you drop your gold out of the carbon .
