    How can I use iodine to recover gold from circuit boards?

    I have used Aqua regia to disolve gold, but it is not as selective as I would like for some of the parts I do. I know that iodine will work, I just have not found the method to drop the gold and regenerate the solution for reuse. I know it was used commercially for a while before cyanide...

    How can I use iodine to recover gold from circuit boards?

    How can I use iodine to recover gold from circuit boards?

    Thanks. Yes I believe copper will drop the gold, but it would render the iodine solution infective for further use. I would like to reuse the iodine solution. I am trying to cut down on chem use during the process.

    How can I use iodine to recover gold from circuit boards?

    I am working on a pilot project to recover gold from circuit boards. I have tried several methods and am interested in giving iodine a try. I know it will dissolve the gold but I cannot find an answer on how to get the iodine solution to drop the gold. Any ideas? Thanks.

    Big Wind Tunnels - It's Not Everyday

    That is a very cool model Cyrus. The stealth aspects of it are interesting. Just curious, How do you test it at higher speeds. Are these tests just used to make sure it can take off and land?
