I'm not sure if I speak for the others or not, but what I have already shown you is all I know at this time.

If you would send me a cashiers check for $5000.00 USD, I will gladly stop working at what I am doing and research this topic and even make a video for you to watch :shock:

edit to add link.

" As far as washing materials like your filters, I'd have incinerated them, screened to remove any potential large items, swept a small magnet through to remove any magnetic particles (which were all dumped in the stock pot), then the material would be placed in a beaker, and covered with roughly 50/50 HCl and tap water. I would then boil the lot for a period of time, usually simply making visual observations that the material had been changed. It's usually obvious. One thing to remember. When you're processing a large amount of material that is akin to dirt, it often will cook dry on the bottom of the beaker, which then forms a very hard deposit, a combination of previously dissolved elements and solids. That usually results in a broken beaker, so my advice to you if you decide to pursue this as I suggest, be certain to keep stirring your material as it heats, and even when it is boiling. Even then, the occasional hot spot will overheat the beaker, which will crack when stirred."

This was from a post made by Harold. The entire thread is here: http://goldrefiningforum.com/phpBB3/viewtopic.php?f=39&t=1143&p=10681&hilit=processing+filters#p10681

I found it by typing "processing filters" into the search box. Then going to the oldest and back tracking.

Thank you

step (1) incinerate
step (2) leach
step (3) precipitate

you now have recovered values

that is what you do step by step --- you want more info then that do a search here on the forum - it has been talked about many times - after you searched & read what is already here & you don't understand something in what you find ask about what you don't understand & we will be more then glad to help you with that

We are not here to be "your" personal teacher

We are refiners helping refiners - meaning we have spent our own time doing the research to learn to do this & we help each other out if we are having a problem or don't understand something new we are doing research on

We are NOT here to be the personal teachers of "want to be refiners"

You have two choices. One of them is chemical extraction, with the other being processing by furnace. Of the two, I recommend the furnace procedure, as it recovers all values, including silver from silver chloride.

If your choice is to use chemical extraction, by reading Hoke's book, it should become obvious to you what an acceptable procedure would be. You can even recover silver from chloride, assuming you're willing to dissolve the silver chloride with ammonium hydroxide. Take note that that process can be dangerous.

Read Hoke---and think about furnace recovery, using your waste materials as a savings plan. Worked for me.
