Question about Geology/Chemistry/Mining Engineering:
If a person or company was to dig a hole or tunnel, how feasible would it be to be able to use every compound that was pulled out of the hole in one form or another?
Dirt is mostly organic compounds and Silica, right?
And for rocks, it depends on the type, but I don't know enough about geology to know what elements and compounds the different types are made from yet (I need to do more research)
