  1. My first thought is to stop adding so much iron. Ideally, you'd only add just enough to be consumed. If you don't have any leftover iron, there's nothing for the bismuth to plate to.
    Also, if you're adding an oxidizer to break down the pyrites, you're also oxidizing your added iron AND your bismuth. Bismuth also has a blue flame — but bismuth oxide fumes are yellow.

    Maybe you're just trying to do to much in one pot, and need to roast the pyrites before you smelt.

  2. u know what i dont care u take forever and have lost my intrest so f off with yah crap yah do im done watching you and your gold u never show for years so get real and get a life!@!!!!!

  3. Get some cheap to free iron hacksaw-dust (file-dust?) instead of your nails at the next metalworker-shop! More surface to react and no mass while pouring.
    And extend the molten time to several hours (expansive, I know.) The pyrit allways contains the gold and leaves it behind.

  4. tip jason @mlmmllc weigh the nails before and after each smelt. and if you can use a sight density device on them should be able to tell if any gold is sticking to any of them, theres some advanced ones where you pre-record the nails(other stuff) then use it after the smelts making sure no gold/silver gets on them. Also check/look back at your older nails for any gold/silver stuck on them.
    The device will record the nails at a 1.0 (an example) but after the smelt it'll go to a 1.5 if any gold goes/gets on them after the smelts.

  5. I see your nails are causing some problems. Maybe you have steel nails not iron nails as you think and that's the main problem. Use a piece of (long) iron rod. You stir with it and can remove it before you pour. Also leaving the iron in your smelt can cause a secondary reaction if your furnace gets hot enough.

  6. Jason, I bought some one gram 99.9% silver bars and use them periodically to test my smelting technique. Use an ore sample that has been proven to not have any gold or silver in it. So far I’m getting back 99% of my silver back. Since you are checking for gold contamination just use one gram gold bars instead. Testing with a known quantity is a well known scientific method. HTH! Love your channel.

  7. You are quickly becoming my favorite you tube channel! I been hiking the east fork of the san gabriel river found a really interesting quartz out crop on a back trail… i know enough to say that it is super mineralized with copper as it has green staining throughout the rock tons of what i believe is pyrite really silvery and sparkles i wish i could have you crush it and see whats in it id go lug some more down the hill lol

  8. Get some (new) battery acid and the iron in those nails will dissolve in a couple minutes. Keep the volume as small as possible. The bismuth will probably dissolve too leaving a purple tinted micro gold solution. Neutralize any remaining acid and dry it down on low heat. Mix with silica flux and smelt. You can mix the solution with the silica for the flux and dry it that way to prevent spattering.

  9. I'm skeptical that the excess gold came from the old, used nails. Was there a bunch of Bismuth stuck on them? More likely you hit a high yield pocket, or the MO guys are not recovering all the gold. I've been sampling a vein that can yield anywhere from 15 ppm to 90 ppm and changes in a few inches. The average Au particle size is 75 microns and the gold is very hard to find with a microscope.

    Do they have professional assays of this material? I've been finding a big difference between a fire assay and a pan-and-weigh assay, especially with gold particles under 75 microns. It seems that the gold really does get stuck/buried by the sulfides when I grind to 60 mesh minus and no finer.

    I've been experimenting with Bismuth, following your direction. It's behaving rather weird. I have a video coming out tomorrow about assaying your gold ore and you'll see one example of what I mean.

    There's lots of experiments left to do on this subject and your work is great motivation and a learning experience. Thanks! — Dave
