    El Dorado County, Need help with 1.5 lbs of found buried mercury.

    I found about 1.5 pounds of mercury buried in a glass fruit jar. Is there anyone near El Dorado County that can help evaluate the mercury? I suspect it is just liquid but perhaps it has some amalgam. Should this be run through a retort? Does anyone have the experience to discern if the material should be run through a retort? Please PM me if you are interested in helping. Thanks.

    With proper protection I would run it threw a fine sieve to see if there is gold amalgam.

    Even a little through a coffee filter would give you some indication what might be there

    My biggest worry before playing with it would be it's history...if anything is mixed with it, why was it buried.....It may be fine, but who knows what home experiments it may have been through. Just thoughts...

    Cant you let the surface oxidize by allowing air to hit it. If it forms a scum or oxidation layer on top it will have other heavies? Hope theres lots and lots of good stuff

    DONT DO THIS!!!! If you do you'll contaminate the surrounding area! And DONT heat it in your oven to burn off the excesses mercury.

    Get a plastic concrete mixing tub and do all your work inside it to contain spills. Wear nitrile gloves and work in a well ventilated area.
    Hg will not go thru a coffee filter easily and the filter will tear if you force it. I use a patch of nylon fabric like from a tent or wind jacket. Lay the fabric in a jar, pour in some hg then wring it out. Any solids like gold will be strained out.
    Its messy, be prepared
    Be sure to post back with what you find

    I was watching a deal on youtube, Cody's lab where he deals with dirty mercury. Sure all precautions should be taken but if there's other heavies wont they keep the mercury from evaporation?

    Use a "chamois" to squeeze the Hg through. Of course using the normal cautions when handling.

    pour it through a 20 mesh screen.

    Its too cold out for it to off gas in any significant way.

    You would only put what stays in the 20 mesh screen in a retort.

    Actually historically, that was (is still in primitive mining areas?) a method of wringing excess mercury from amalgam lumps before it is fumed off with heat in a retort or in a pan over an open fire, etc. The bottle appears to be mostly if not all liquid mercury so maybe what Goldwasher said.

    If it can't be grown, it must be mined!
