Case Type


Full Tailing And Crushed Stone Backfill System Case 



Project Description


The first complete tailings and crushed stone paste backfill system in Central Asia (with core equipment being the HGBS100.15.320
backfill industrial pump and an 18-meter deep cone thickener), with a system capacity of 80m³/h, a conveying distance of 1300 meters, and an annual backfill volume of 260,000m³. 




Project Outcome


The use of deep cone thickeners for one-stage concentration of full tailings has resolved the high cost issues associated with the previous tailings filter press process.
