Yingping Mining Section Open-pit Tailings Backfill Treatment of Goaf Ecological Restoration EPC Project

The project was completed and put into operation in 2022. It adopts phosphorus tailings backfill comprehensive utilization technology for design, employing an economically feasible, low-cost, safe, and environmentally friendly full-tailings backfill process for treating goaf and ecological restoration. The phosphorus tailings are processed to meet Class I solid waste discharge standards. The process is simple, feasible, and extremely low-cost. The treated tailings that meet Class I solid waste discharge standards can be stacked anywhere without the need for impermeable membranes, enabling ecological restoration of open-pit mining pits, effectively reducing tailings storage costs, and saving maintenance expenses for tailings ponds.
