Tip #2
How to recover gold from the ultrasonic tank.
Pour the solution through a paper coffee filter that is inside a strainer. The solution then runs into a large can or bowl. Next use a paper towel to wipe the sludge out of the tank. Place the coffee filter and paper towel inside a plastic trash bag and when full send it to a refinery. The used solution can be poured back into the ultrasonic tank, then add a little non-ammoniated concentrate.
