My brother told me about these plants. He said that mines would plant them after they've already mined out as much of the ore as possible. They're really good at getting out that last little bit but they're not the first thing to reach for from a mining perspective.


Do they plant them underground? Using artificial light? How are the minerals extracted from the plants? How is this profitable?


Mines are almost never underground nowadays. They dig a big hole, or cut off a whole mountaintop.
