When an open pit mine closes down, it is typically reclaimed and rehabilitated to restore the land to a safe and usable condition. This process may involve filling in the pit, grading the land, planting vegetation, and implementing measures to manage any remaining environmental impacts such as water quality issues or erosion. The goal is to minimize the long-term environmental and safety risks associated with the mine site.
