Phytomining for Artisanal Gold Mine Tailings Management

Mine tailings are generally disposed of by artisanal and small scale gold miners in poorly constructed containment areas and this leads to environmental risk. Gold phytomining could be a possible option for tailings management at artisanal and small scale gold mining (ASGM) locations where plants accumulate residual gold in their above ground biomass.
