Sulphide removal: Extract sulphide minerals such as pyrite from tailings to reduce acid-generation potential.
Controlled storage of reactive material: Store pyrite concentrate or other reactive material under engineered conditions that limit oxygen exposure and oxidation.
Dredging and stockpiling: Remove accumulated mine-derived sediment from targeted river areas and transport it to engineered stockpiles.
Rehabilitation and revegetation: Use native vegetation, suitable surface materials, erosion control and organic amendments to stabilise disturbed areas and improve ecosystem function.
Environmental monitoring: Monitor pH, sulphate, metals, turbidity, sediment, vegetation and aquatic ecosystems to track environmental change and rehabilitation progress.
Source control → Sulphide removal and controlled storage of reactive material.
Physical management → Dredging and engineered stockpiles where appropriate.
Chemical management → pH, metal and sulphate monitoring and acid-generation control.
Ecological rehabilitation → Native vegetation, erosion control and suitable organic/surface amendments
Long-term monitoring → Water, soil, vegetation and aquatic ecosystem monitoring.
