- •
Chemical stability of sludge from extreme polluted AMD neutralization is assessed.
- •
Severe discrepancies in well-established international regulatory tests were observed.
- •
Metal release from the sludge is strongly controlled by environmental conditions.
- •
High concentrations and readily extraction of metals pose the waste as metal ore.
