Dolores Mine
|
Type: heap leach pad
Place: Dolores Mine (Mexico)
Surface: 20 380m² // 219 368ft²
Product: COLETANCHE ES3
BACKGROUND
The Dolores mine is a large silver mine located in the north of Chihuahua, Mexico. Dolores represents one of the largest silver reserves in Mexico and in the world.
This expansion was developed under a number of constraints that favored COLETANCHE. COLETANCHE was placed on the new heap leach pad bottom lining.
REASONS OF CHOICE
In this project, the COLETANCHE geomembrane promotes:
- High friction angle (34 degrees)
- Good puncture resistance
- Lack of quality clay in situ to develop a proper pad
- Silver reserves
- No time and weather constraint because the insallation is possible in extreme weather conditions (rainfall, wind, cold temperature down to -40°C or -40°F).
