About
Mining leaves vast quantities of crushed waste rock containing unrecovered valuable metals and capable of contaminating surrounding land and water. Gigatonne Bio uses genetically engineered bacteria that release organic acids to dissolve this material, freeing nickel, cobalt and platinum-group metals. The process also releases magnesium, which reacts with carbon dioxide to form stable magnesite, storing the carbon permanently. Tested in a bioreactor, the approach could recover additional resources, reduce hazardous tailings and combine critical-mineral production with long-term carbon removal.
