Efficient gold recovery by microbial electrochemical technologies
Bioelectrochemistry, 2023 The applicability of microbial electrochemical technologies for the recovery of gold was investigated. Two-chamber microbial fuel cells (MFC) with bioanodes buried in sediment were used in two operating modes. The cathodes (gold foil or graphitized paper), submerged in HAuCl4, solutions, were short-circuited with the bioanodes, and thus for the first ...
