Bioleaching of Au and Cu from a toxic MPPCBs waste using
- •
Response surface methodology was used to evaluate and optimize three main factors.
- •
At optimal condition about 72% of Cu and 65 g Au/ton MPPCBs were extracted.
- •
Cu elimination from MPPCBs with high ratio of Cu/Au can improve Au recovery.
