- •
A rainfall simulation study on mine wastes was performed to evaluate As release.
- •
As is being mobilized as colloidal scorodite for 50 min of simulated rainfall.
- •
Nanometric colloidal ferrihydrite acts as As(V)-carrier phase downstream.
- •
Scorodite-rich wastes are releasing As by weathering and erosion processes.
