Reprocessing Gold Tailings by Gravity Methods

Tailings originating from the gravity concentration of a gold ore containing about 14 g/t Au have been treated by various beneficiation methods. These tailings have been screened on the 147 and 74 micron sieves and the two coarsest fractions have been separated on shaking tables with unsatisfactory results, but the concentrates have been examined in polished sections for mineragraphic analysis.

Phytomining for Artisanal Gold Mine Tailings mdpi

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.
