Ok Gents, I've seen many posts about people needing to know how to process gold ore.
My friend and I have sent off a 6 lb sample for an assay. The results are added here.
To begin, my friend has tried several times (before the assay was sent) to melt some of the gold that he collected out of the same batch. He said that he wasted 2 cans of Mapp gas, and it still wouldn't melt. What would keep the gold from melting?
Also, his crucible has turned blood red and purple in places. I have not tried to melt any yet. I have ran a batch of the ground (powder) quartz in HCl and bleach to dissolve any and all of the flour gold.
My solution turned orange which I believed to be iron (this later confirmed by assay)
I tested the solution with a fresh batch of Stannous and there was no color change at all.
So either there was no gold, or there was something in there preventing the gold from representing.
Now, I know there are oxides present but I don't know how to deal with them, other than roasting. So, Harold, Butcher, and all who know.... by looking at the assay results can you advise me on how best to separate the gold, platinum,Palladium, and silver?
Here are the assay percentages.....
Fe......46.3%
Cu.....7.4%
Zn......16.4%
Pb......3.2%
Mo......15.2%
Ru......4.1%
Ag......7.5%
Au......12.7%
Thanks for the help and advice.
