Asteroid Mining - Massachusetts Institute of Technology

Platinum-rich asteroids may contain grades of up to 100 grams per ton, 10-20 times higher than open pit platinum mines in South Africa (Sonter, 2006). These ore grades mean that one 500-meter-wide platinum-rich asteroid could contain nearly 175 times the annual global platinum output, or 1.5 times the known world reserves of platinum group ...
