Minerals | Free Full-Text | Phytomining for Artisanal Gold ...

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.

2013-4-15 · Plant the crop on soil that contains gold. The waste piles or tailings surrounding old gold mines are a good place to look. Conventional mining can''t remove 100 percent of the gold from surrounding minerals so some gets wasted. Once the crops reach their full height, treat the soil with a chemical that makes gold soluble.
