Since ancient history, mining has been a dirty business. While we’ve developed new tools, chemicals, machines, and techniques, most of today’s mining still boils down to digging in the dirt. As the world ramps up production of the technologies it needs to move away from fossil fuels, this widespread disturbance of Earth and ecosystems will continue in the accelerating search for critical minerals like lithium, cobalt, nickel, and rare-earth elements.
But what if there were another way? Or, better yet, many other ways. After all, the minerals we need aren’t just buried underground. As the basic building blocks of much of the world’s matter, these elements have accumulated everywhere: in plant life, in the ocean, in our industrial waste, and even in rocks hurtling through outer space. While the ability to pull enough minerals from these sources to power the energy transition is still a long way off, scientists and entrepreneurs are hard at work trying to find out if each of these sources can compete with traditional mining methods. In the process, they’re also raising challenging qu... Read more
