Gold particles clogging tubing

I have used Simple Green to break surface tension of flour gold because the gold was floating. Simple Green will foam. A dishwashing detergent may work without foam.

Try using anti static spray compound such as the ones used for laundry. I am not sure if this is going to work but this is a cheap experiment to try!

let me know how it turns out

Thanks

simplest logic could be static electricty. It as to be dischaegd so as not to attrat particles.

hmm how to go aut.Charge is so less, as much generated by hand rubbing.tuch of metal, close one or may be water, I dotn know but can be tried

It is possible that either the gold dust or the tube has charge on it.

Are you using distilled water or DI water? If so, the water passing through the glass tube will build up a static charge. You may need to mix the water with something to counter balance the electric potential.

Sorry to here of your situation. I use to work in a process environment years ago, our solution to the static build-up, was to completely ground the system. All the transfer tubes had a grounding strap, and we ended up monitoring the potential from the ponds to the working tanks. As the solutions transfered from section to section, each solution had its' own density and molecular disimulars. Some mixtures had a greater potential in generating a static charge. Some sections of transfer channels required more grounding, which was due to the overal length and transfer rate of that particular solution.

Reccommendations, take a reading of the material at its primary bed, before you transfer it into the system. Then take casual charge measurements through out the routing of the solution. You might even need to magnetically charge the solution as a deterrent to it being attracted to the transfer tube. Good luck, Maximo

Use a product like Jet Dry or Rain X on the glass. It is a water based plastic that will coat and fill in the pits if not too large. I am not sure how it will work with the medium your using the move the gold flakes.

Check for any (+ or -) charged in the gold flakes.
