When Indonesia’s significant open pit mine needed an efficient dredging system, they turned to Dragflow.
The challenge was complex: removing highly concentrated sediment from the bottom of a basin and transporting it to a higher area of the mine, all while dealing with acidic water with a pH of 3. Maintaining the reservoir’s capacity was crucial to keeping operations running smoothly.
To tackle this, Dragflow provided a DRH Cable dredge with an HY85/160HC pump and two EXHY20 side cutters, designed with special materials to resist the acidity.
This system proved to be a game-changer, pumping up to 800 m³/h of material and transporting it over 500 meters, ensuring efficiency and reliability even in such a demanding environment.
