How it works
It identifies acid-producing rock, limits its contact with water and treats the affected waters.
Mining management includes exploration, extraction, treatment, community relationship, closure and subsequent surveillance.
When does it make sense?
- The risks of the deposit and site are assessed
- There are resources and responsible during operation and closure
- Results can be reviewed independently
How to apply it
- 1
Delimit the measurement and measure the starting position.
- 2
Apply the measure with competent personnel and check for site-specific risks.
- 3
Follow results, maintain the solution and correct unwanted effects.
Potential benefits
Lower risk of contamination
Improved territorial protection
Close more responsible
Limitations and precautions
- The benefit must be verified under the actual conditions of application.
- The avoided damage depends on the design and maintenance throughout the life cycle.
- Extraction continues to involve impacts that require prevention and limits.
