There is an article in Saturday WSJ about a very old Zinc underground mine outside Clarksville TN that is planning to upgrade their processing plant to recover the “waste” Gallium and Germanium that is present in their Zinc ore.

Remember when coal miners were told told to “learn to code”
because no mining skills would be needed in the future ?

Just the amount of Copper needed for the world’s “clean energy future” boggles the mind.

If you ever visit “Copper Hill TN” be sure to see the photograph in the museum where SO2 gas from the Smelter killed all the plants in a huge circle surrounding the smelter exhaust stacks.
