More Mining at Home Is a Win-Win for Environment and Defense
Rare Earth Elements are not rare at all. They are pretty much anywhere. What’s rare is the conditions to extract them out of the dirt in commercial quantities. So, any sludge that is super loaded with them should be commercially interesting. Maybe the US (and the rest of the world really) should take another look at methane hydrates. Subsea methane hydrates mining produces just the kind of sludge loaded with all the stuff we are looking for and who knows, we might make those hydrates commercial in the process. What say you?
