Mine Tailings: The Cornerstone of Safe Mining Operations

One of the most common methods for managing mine tailings is the construction of tailings ponds or tailings storage facilities (TSFs). These large-scale repositories serve as containment areas for the collected material, allowing for the settling of solid particles and the retention of water before eventual disposal or treatment.
