    Gold Fingers - How to Recover Gold from Electronic Scrap



    Published on Dec 19, 2013
    http://http://www.goldnscrap.com In this video tutorial i'm showing how to recover gold from electronic circuit board scrap. Specifically the gold plating that is found on the board connector edge - A.K.A the "fingers".
    This video is a complementary to the complete written tutorial on Gold-N-Scrap website (direct link below)

    The process applies to other kinds of gold plated itmes, given the substrate is unreactive (such as PCB, ceramic, glass etc'...). This process is less suitable for metallic items that are gold plated such as gold plated pins and gold filled items, though it will work with much effort and large consumption of acid.

    Post a comment and let us know how much gold do you think this recovery process yielded.

    DIY Gas Furnace - Melting Gold and Silver



    https://youtu.be/0XlCcQMRM9E

    Published on Apr 23, 2014
    http://www.goldnscrap.com This short video demonstration shows how i built a small gas fired crucible melting furnace with some basic tools and equipment.
    This makeshift furnace is capable of melting couple of pounds of Gold, Silver and Copper in one melt easily.

    I already had most of the equipment and the only thing i actually needed to buy for this project was the insulation blanket.

    The silver that was melted in this video was refined using electrolytic cell and the purity is 99.99+%. The crucible used in this video holds a bit less than 3 lbs. (about 1.35 Kg) silver.

    The underwater footage was taken using a GoPro HERO 3 (Black edition)

    -------------------------------------

    Hope you guys learned something new and enjoyed watching this video as much i enjuyed making it.

    If you have built a similar furnace, let us all see it - Post a link to a video or pictures of your furnace here in the comments section below.

    Published on Jun 16, 2012
    http://www.goldnscrap.com A short demo - manual casting of one ounce gold bullion bar.
    Fuel/Oxy torch and a graphite mold were used. The gold was melten in a silica crucible.

    p.s. - sorry for the disturbing background noise... i didn't realised how loud my fumehood fans are...

    Melting Silver - 32.15 Toz (1 Kg) 999 Bullion Bar



    https://youtu.be/bEGkoTc17Zw

    Published on Sep 2, 2012
    http://www.goldnscrap.com/index.php?o... Melting Silver, Here's a short demonstration of meltdown and casting of a 1 Kilogram (32.15 Troy Ounces) Silver Bullion Bar.

    Please note, the Silver was melted inside a graphite crucible (keeps Oxygen out) using an electric furnace. The actual pour of the metal is done all the while a propane flame is blazing into the mold cavity. Again, to prevent Oxygen absorption by the Silver (otherwise it will "spit" upon solidification).

    Also note, as this is a safety issue as well as a technical demand, that the mold was pre-heated prior to taking this video by placing the mold on top of the furnace lid.
    Molten metals being poured into a cold mold can literally "explode" out of the cavity all over you and the surrounding work place, posing a great fire and injury risk.

    The mold was also seasoned prior to taking this video by coating it with a layer of soot from the propane flame.

    This particular mold was made by me, unfortunately, it seems that i chose the wrong kind of graphite to work with (too porous), hence, the not so perfect surface finish (as you can see, the surface is slightly dimpled).

    But all in all, still nice result. :-)

    Here in this video, you can watch the a first Silver Refining steps:

    How to Recover Gold from Integrated Circuits Chips



    https://youtu.be/VZganYmR0-w

    Published on Mar 5, 2013
    http://www.goldnscrap.com Here's a short video demonstration on the process of Gold Recovery from scrap Integrated Circuits Chip (epoxy based).

    Please note, the process shown here relates only to magnetic chips (magnetic leads).
    The leads (pins) from this process are processed together with non magnetic copper based chips. I will make another tutorial about that in the near future.

    Also, do know that i do not advocate the use of inciniration of plastics unless it can be done safely and in an environmentally friendly fashion.
    If you can't incinerate right, DON'T DO IT !


    Any comments are welcomed.

    There is one problem with recovering metals from scrap and fabricating them into ingots. No matter how pure you make them and how beautiful they look, no one is going to take your word or stamp for how pure they are - or even what metals they contain. Nobody. And no one will pay you what they may be worth unless they are stamped with a recognizable hallmark. If you do sell them to anyone other than a refinery, you will take a steep loss. They will have to be remelted to be properly assayed anyway.

    Unless you just want to play with the metals as a hobby, my advice would be to take your scrap jewelery, contacts, fingers- whatever- to an honest refiner as they are. Seriously, you will get just as much for them and you will save yourself a bunch of time without fiddling with dangerous chemicals and the associated risk. And most likely, the recovery rates will be higher.

    And instead of taking payment in cash, if you wish, you should be able to swap your scrap for stuff they were getting ready to put in the furnace anyway, like junk (90%) silver coins or any number of other recognizable pieces - without paying a premium for them.

    It really is a hoot to watch the refiner weigh coins, including silver dollars instead of counting them when trading for payment.

    Just my 2 cents.

    Great post D-Fenz! One thing I would add is don't send silver dollars to the refiner!

    Full Server Tower Scrap for Gold Recovery
    eWaste Ben



    Published on Jan 28, 2016
    Server towers are big and heavy, a lot of the weight is in the steel tower itself so when buying scrap server towers you need to take that into account, server blades are different, they usually have larger motherboards and weight less in steel.

    Copper Pancake from Scrap Copper Wire
    eWaste Ben



    Published on Dec 30, 2016
    Copper Pancakes from scrap copper wire are a fun little project i'm trying out, basically to use as plates to engrave pictures onto if I can get them flat enough.

    This was my first attempt at pouring a copper pancake and was surprised at how easily the cast iron pan cracked, will definitely need a better quality pan and more copper next time.

    oh well, it was a fun experiment.

    Copper Ingots are starting to become a hobby of mine, scrap copper wire is abundant so i'm pouring lots of different kind of ingots.

    Here I tried to use another cast iron mold, the last video on copper pancakes cracked the cheap modern cast iron pan but this vintage muffin tray held up well.

    Keep scrapping!

    Gold Chips from Computer Mice
    eWaste Ben



    Published on Jan 6, 2017
    Gold recovery items come from all sorts of electronics, Here I open up some computer mice for their circuit board which usually have a gold ic chip type thing with gold legs and gold bonding wires inside.

    Not bad if you compare them to regular dip ic chips which may or may not have gold inside, well worth busting open all your scrap mice to get these to add to your gold recovery collection.
