Blue Bowl separation of Pulverized PCB Components for Gold Recovery 

In my opinion, it may be better to turn on the water after depositing the material to the bottom of the bowl. Alternatively, you can use a pipe (with a taper cut at the bottom end) to deposit the material to the bottom of the bowl while the water is running.

You also need to run a magnet to get all the metal out before running through blue boul

Use dish soap because very fine gold will float

Use some dish washer rinse aid in your water to stop the small gold particles from floating.

Should have tried dawn dish soap to drop small flakes you lost

I was thinking about that, interesting result. What kind of material is that? Looks like mix of all possible stuff.

My bf has one of those bundt pans, er uh... I mean "blue bowls". 😂

Have to run it through the screen losing your gold because some of the bigger stuff heavier than your gold

You have to know a cupellation.

Step one, toss everything that floats

boy oh boy..this is a total disaster... first of all..your material should be washed down to keep the water clean so that you can see how the bowl is reacting..second..you should of classified besides 30 mech..60 mech and 100 mech and run them seperately... third..never put son much material in the bowl...you need loads of help..four...remove that valve by a gate valve..i can go on and on...
