Heya... Thanks for sharing ! Really good work... As usual may i say !!! ;) Ag and some contamination must be the add in final weight... But it's also why it's best to refine by yourself... Always a pleasure to see your videos ! And i bet you will have a lot of surprises if you refine jewelery stuff... Enjoy !!!

Im so sorry if this is a stupid question. I am still very new to this and just found you can refine gold this way without chemical process which i plan to do, but would like to try this first. Anyway, would you be able to do the same with zinc instead of lead to leachch out the base metals and use some plaster as the cupl or using a regular sil crucible to pull out the base metals? Again, so sorry if this is a stupid question. I am willing to get the needed items, just wondering if i could use what i already have on hand. Thank you so much for sharing your videos amd showing everyone the process and how to. It is very much appreciated.
@OwlTech3334 жыл бұрын
The question is not stupid. Plaster (gypsum) will not work as materiel for cupels(I've used cement, bone ash, magnesia, hydrated lime, heat treated limestone powder etc.) , zinc will form an alloy with some of the base metals, copper being the most troublesome for this process. The only substitute of lead that I know of is bismuth (when talking about cupellation). By cupellation you can remove only base metals, if as in this video you have AuAgCuZn alloy, after cupelling you'll be left with an AuAg alloy.

I was just passing by , I am sorry i am not sure i get this as it really looks to simple 😂 can i actually just use cement powder and fishing sinkers (lead) + heat to leach the impurities out eg the led leaches out the other base metals etc then soaks into the cement powder leaving a higher purity gold ? , 5:1 led to gold in compacted cement bowl and just head till its gold left ? , is it really this simple , ive not dared try to smelt any of my nuggets or anything but if it is this easy i would really like to male some gold marron and snakes etc from my nuggets and old jewellery 😃, also would this be possible in an electric smelting furnace if you pack the crucible 💁♂️, thankyou 😁

It's lead to impurities ratio rather than pb:au, you must have enough lead to oxidize all base metals. If you have enough lead you can cupel gold filled although IMHO it's better to strip the gold in a lead bath.

@OwlTech3333 ай бұрын
If you breath the smoke this could be one of there most dangerous techniques out there, just like inhaling acid fumes or falling into a volcano! So NEVER breath the smoke, inhale the fumes or step in the lava! For cupellation you don’t need acids, but you may need other chemicals like borax, Portland cement, sodium nitrite etc. The purity of the gold you get depends on the metals your gold is alloyed with if there are other PM in the alloy they will remain with the gold, if only base metals are present with the gold those skilled in the art can achieve 99+
