done stripping in a cell
Chanted the cell then added (acid into water)what was left slimes and sludge's into about 400 ml of h20
I had 3 beakers of cell slimes settling and they had lots of floater raising and sinking. Most the time it took 2 days for them all to settle.

any fast way??

i believe i have read that sulfuric acid and peroxide is not a good combination of chemicals to mix.
 
The "stupid part deleted" was not really stupid, only potentially dangerous. Again we learn, never just try blending something without being sure. :) At least you had rinsed your gold by this pretty well.

edit: you've been lucky that your sulfuric was very dilluted, though

You can make a charmin plug out of fiberglass and filter your acidic solution with your slimes in that way.

You should compact your filberglass fairly tight so that it will retain the anode slimes. You will probable need a vacuum filter system of some type. You can also, with the correct filter media like fused quartz materials (Wool, felts, etc), use a coors buchner filter to achieve this as well. Here is a company that sells this type of filter media:

Also some types of Polypropylene felts and wools will work, I believe Lou has posted the name of a company that sells that type of filter material, I have purchased from the company he recommended but I cannot for the life of my remember the name, and I am not near where I keep the information. I would suggest asking Lou, or when I'm back home I can post that information if there is interest.

The idea is that you can filter through this medium, and because it does not dissolve in the presence of strong and/or concentrated acidic solutions, you can then introduce it to AR, or other acid solutions so you may dissolve or selectively dissolve the different components of your anode slims accordingly. You have to make sure you rinse them well to ensure all the solution is rinsed out, but after you can re-use them again.

I keep different types of felts, for different applications, cut to size, for my buchner filters and keep re-using them over and over to good effect.
