Technological advances in mining waste. In partnership with the University of São Paulo in Brazil, we are working to identify "copper eating" bacteria and fungi capable of absorbing copper from our tailing dams. The research has the potential to significantly boost copper recovery from waste, revolutionizing the industry in the process.
