Hello Virgina Gent,
It sounds like you have a great inside source to scrap. Aside from the gold that it contains, scrap metal yards would buy the rest of those units for the copper and other metals that they would contain. I know, I have sold quite a few vcr's, cd players car stereos, CB's, etc. at a scrap yard here.
Making your wife a Gold band would be cool, and hope that you recover enough gold to do so. I took a jewelry class as an Elective back in High School, so I know how easy it is to do, as well as how fun it is to make your own rings.
As for myself, I am a "Rockhound". lol!
I have been a prospector since I was 6yrs old, and have found a few pockets of gold within the sand and gravel in ground out holes in the Bedrock of stream bottoms. Panning out those sediments is where I have had the most luck while out prospecting stream sediments. As far as Hardrock goes, I have located a deposit that Assayed out at 1.17 oz tn Au, and 3.51 oz tn Ag, Though as of yet have not started to mine it. I am still looking for a market for the ore concentrate, I do not want to sink a bunch of cash into it without a market for the concentrated gold bearing ore minerals.
I am an Assayer for Gold and Silver, as well as a pretty good amature petrologist/geologist/mineralogist.
I can identify Rocks/Minerals as well as thier associations with each other, and the type of vein systems they are associated with.
I like Chemistry as well, and as a result I have an extensive knowledge of how to test Rocks/Minerals to identify what metallic, and nonmetallic elements that they contain. Quite useful as an Assayer, and prospector.
I am also an Adventurer at heart. I love the outdoors, and exploring Caves/Old Mines, Prospecting, Rockclimbing, Hunting, Fishing, Rafting, Hiking, and Camping are things that I do enjoy doing.
Anyway, Good to hear from you, and again, welcome to the Forum!
If you have any questions about Rocks/Minerals, and testing them, I am the one here to ask.
I am "The Rock Man", lol!
Sincerely; Rick.
