Overview of fungal bioleaching of metals

This article has reviewed the progress that has been made in bioleaching research of metals using filamentous fungi. This review has focused on fungal bioleaching from various metal sources, including mine tailings, electronic waste, solid mine wastes, spent catalysts, and low-grade ores. Filamentous fungi are used in bioleaching due to their ability to secrete organic acids and facilitate the solubilization of metal ions from the solution phase.
