That is a real neat find for a relatively low price. An no doubt some gold there mixed in with the other mineral rocks, stones etc....
Curious how much actual gold is in them, and if there are any chances it could be a significant amount. And if so, how would someone go about separating it from the materials there that are not gold?

@Silverhawk You would need to crush the rock down to almost a powder. There are then 2 options to remove the gold. Mercury-Crush rock to a powder-dump into a bowl of water-add small blog of mercury-mix for a while (mercury will pick up all the gold, even the stuff you cant see with the human eye)-evaporate the mercucry in a retort-boom....you have pure gold. These videos will show to whole process from start to finish in alot more detail then I just gave you. The link is part 1 of 4 WATCH THESE VIDS AS THERES SOME VERY IMPORTANT SAFTEY INFO http://www.youtube.com/watch?v=KL9deyMSzs8#2- Chemical Leeching I dont know much about it other then I THINK it uses formaldyhide....but I've also seen systems that claim you can buy everything needed at your local grocery store and hardware store. |

I know very little on that most interesting subject, but I am pretty sure when you start messing with those chemicals, it can be very dangerous via the chemicals that one could breathe. I say this before watching the video you provided, but I am going on a memory from a post here from many months back....

Yeh, I belive the videos were paid for by a group of people who were worried for peoples safety. So they did the vids to show people the dangers involved and also how to do it safely to minimize risk. If you do as they say its accually harmless.
Part 1+2 are how to build the device 3+4 show how to use it.

They are worth very much more as mineral specimens than they would be for their gold value.
Well worth keeping as such.

I'm not melting these down, no worries.
I have several natural gold nuggets too.
Melt them, you destroy specimen value which is much more than melt.

Very cool pick up there! I have to agree keep them in the original form. Looks like one of them has a nice chunk of quarts on it.

@CWalker...
Yes, you can use Hg to selectively extract Au from powdered rock but be aware that Hg has a significant vapor pressure, bio-accumulates, and is quite toxic. Having the proper lab equipment, including a good fume hood, would be essential to doing this safely. The best way to pull off the Hg might be to use a glass distillation system with a water cooled condenser to catch the Hg and control the fumes. Pulling a slight vacuum on this system with a water aspirator might be useful.
Chemical extraction via the use of sodium cyanide solution to complex the gold, filtering, breaking the complex to release the gold, and then filtering, washing, and drying the final product. While this is possible it is quite hazardous and should not be attempted by anyone without the proper knowledge, experience, and equipment. A fatally toxic dose of cyanide is quite small and accidental poisoning of an inexperienced person is a highly likely outcome. Additionally, cyanide solutions are unstable below about pH 8 or so and can give of highly toxic HCN gas. Yes, this is the same gas used is some of the "gas chambers" to perform executions.
