This article examines botanical alternatives to mercury-based gold recovery in artisanal mining systems.

The continued use of mercury, a potent neurotoxin in artisanal and small-scale gold mining remains one of the most persistent environmental and public-health challenges associated with mineral extraction. Despite decades of awareness, mercury amalgamation persists due to its simplicity, low cost, and accessibility, particularly in low-resource mining contexts.

Recent research has explored botanical and plant-derived chemical systems as potential low-toxicity alternatives for gold mobilization and recovery. When evaluated through solution chemistry and controlled processing frameworks, these approaches offer a scientifically grounded pathway toward reducing mercury dependence while maintaining practical viability.
