Keep readingAh, yes
I'm trying to understand the whole concept behind it though. It would really make it easy for me to know how exactly it all works.

Not bad, but it seems it has been a bit to cold to melt properly.Over the weekend I used the HCl/H2o2 technique to dissolve some impure old powder and IC bonding wires.
I used about a total of 78 ML HCl and 104 ML H2o2.
Below is the log I created during my process. The end result, Some dark grain powders remained on the filter paper, (Even IC wires went in solution) not really sure what they were even though it took around 2 1/2 hours to call it an end. Will share a picture of the filter paper.
Would love anyone to give in any feedbacks, better suggestions on what I could have done to ensure complete dissolution in a rather shorter time than it took.
P.S. After melting and cooling, what can be seen on the piece is dark green and not black. Not sure what that is too. And there is some borax still stuck onto it. Has been left in distilled water for now.
My first official harvest
Yep, I really struggled to melt it. Going to try and use other DIY methods, pick up some more useful information around here and try and make sense of the best method that could be brought into play here.Not bad, but it seems it has been a bit to cold to melt properly.
For pure Gold powder, borax is not needed.

Yes. Please find below.Do you have a picture of the crucible after the melt.
You took way to much borax.Yes. Please find below.
Yes. Please find below.
Yes sir this is indeed very true, I first used a coal burner but that didn't function for the same, maybe I was making some mistake. Then I moved to a butane gas torch. I'd left an opening in the duct where I inserted the nozzle end of the torch and enforced a fire circulating motion in the furnace. It worked better than the burner and as I mentioned earlier, the gold would get stuck onto the bottom and would be impossible to pry it out. Thr borax addition was the only option left to pull it out.You took way to much borax.
If your flame is too weak, you won't be able to melt that much borax and the gold.
From the pictures, I fear there's more gold stuck in the borax on the bottom of your crucible.
Without a doubtSomething tells me you're due for a new crucible though.
Ah yes I did, after leaving the gold in distilled water and constant stirring for 2 days. It cleaned up pretty much by itself. It's weight eventually came down to 0.48g. still has some left onto it, but I'm more concerned about the borax left on my crucible for any value underneath itIt would kind of give us an idea of/if there was any contaminates in your gold.
I'd try to put the whole crucible into diluted sulfuric acid (5-10% at 30-40Ā°C).Well yes, i did use too much borax here. What is the best suggestion here to get rid of it to try and recover whats buried down there?
Thankyou so much for the clear direction, will give it a try this weekend inshaAllah.I'd try to put the whole crucible into diluted sulfuric acid (5-10% at 30-40Ā°C).
It will take a while but it should dissolve the borax and liberates the gold.
After everything came out of the crucible, decant the solution, dry the gold and melt it.
As long you don't dispose anything, the gold is still thereā¦ I guess, you'll able to recover 0.3 to 0.4 grams.
Good luck!
Inshaallah Habibi!Thankyou so much for the clear direction, will give it a try this weekend inshaAllah.
We have a no politics and no religion rule in here, so please drop your religious referenses.Thankyou so much for the clear direction, will give it a try this weekend inshaAllah.
Please use a polite language in here, no need for mocking.Inshaallah Habibi!
Yes sir, I'm aware of the no political or religious rule here, but no offense here its just a way of saying "by the will of God", nothing more nothing less. I don't see anything religious in this. Anyone can say it, no harmWe have a no politics and no religion rule in here, so please drop your religious referenses.
Ok, good.Hi Yggdrasil,
It wasn't meant religious in any kind.
Beside "by the will of God" it may interpreted as "good luck!".
The correct translation of "Habibi" is "my dear". In youth slang it means "friend" or "brother".
