Dear Friends,
I have spending some time to collect gold from rivers. Now, I have around 300 grams.
Last time, we got 98 grams and we sold the gold, the shop make metal out of it. And they declare the quality is 89% of gold. However, to a miner friend there, said, he claim it is usually 91-92%.
I do not know what is the other content of the metal, and I need some advice, whether there are simple ways to increase the gold quality. Now the 300 gram gold is as the attached pic. Could I use Chloride acid or other kind of acid? I have the burner (propane+air), chemical bottle, crucible.
Thanks very much in advance.
