This start-up rescues metals from mining waste
Tersa Earth employs a cutting-edge biotech approach. It puts ‘microbial fuel cells’ into mine tailings which are the waste materials left over after mining. These microbial fuel cells contain micro-organisms which generate electricity. The current causes metals dissolved in the tailings to become solid deposits, enabling the recovery of minerals and metals such as copper, gold and iron.
