Mint Innovation

Mint has developed a pioneering biometallurgical process that utilises microbes to extract gold from complex, low value feedstocks such as electronic waste (e-waste). 

E-waste is the largest growing waste stream in the world with a metallic value of ~ $60 billion USD in 2016. Most of this value is currently lost in landfill or to the overseas shipment to pyrometallurgical facilities for processing. Mint’s patented low cost process creates a local opportunity to extract significant quantities of gold from e-waste.
