Application scenarios
Reduction of Surface Tailings Storage
Sustainable Use of Non-renewable Mineral Resources
Prevention of Surface Subsidence
Enhanced Mine Safety and Operational Reliability
With the increasing scarcity of surface resources and the non-renewable nature of minerals, backfill mining has become the future development trend of the mining industry. Tailings backfilling not only reduces the surface storage of tailings and protects the environment but also fills mined-out areas, significantly mitigating the risks of surface subsidence and greatly enhancing mine safety.
Solution
The concentration of backfill slurry significantly impacts the compressive strength of the backfill body and the overall backfilling cost. The primary method to increase slurry concentration is thickening, achieved through thickeners or vertical sand silos. In tailings backfilling, polyacrylamide is mainly used to enhance the thickening efficiency of thickeners for tailings.
