A pic of part of a stamp mill at the Yellow Metal Mine in the high country of Nevada co, Ca. Notice it was made at the Miner's Foundry
in Nev. City. This building still stands, and serves as meeting place for all the environmental groups who hate miners and mining, while
fundraising to "save the sierra". Pretty ironic, don't you think?
another subject: - if you browse through the rest of the photos, you can see the "sulphide" nature of the ore. In 1865 there was a
major rush to this area, but they ran into "refactory ore", which meant they couldn't just crush out gold so the district went belly up
in a few years (nowadays they use heap leaching with cyanide to process). I wonder how much natural oxidation has taken place over
a 140 years? That is, could you recover some gold off the dump by just scraping the rust off?
last - just found this site yesterday. It has lots of research potential, guys.
