diy quicksand concentrator PRO PDF Tutorial

[daniel2015]

This fluid bed thingy is really great! Just built two diy quicksand gold concentrators with household stuff and tested them. They work amazingly good! I've checked also the tailings and missed only two very very tiny micron gold particles. Btw. Im using a 12 Volt 750GPH bilge pump.
Here is a simple PDF tutorial. Don't laugh I've tried one of these painting apps on my phone to draw a quick sketch

At first I wondered what the dustpan was for, but I see it catches and directs your water overflow into the bucket, along with black sands and other lighter material. Are you screening (classifying) your material first? I would guess you are...to what size? Pretty small, I would think since your gold is small.

Where in Germany are you? I am curious since I did some gold washing in Germany 25 years ago. I was working near Goldkronach and Goldmuhle in Bavaria.

@GoldpannerDave yes Im classifying to Mesh 8 and it works great! Near munich in Bavaria :-)
Right now Im thinking about building a much bigger concentrator to push 6 to 8 cubic meter sand through it.
