Experimental research on resource utilization of iron tailings powder in backfilling engineering by Guo-Hua Yuan, Yun-Shi Yao, Pu-Gang Zhang, Wei-Guo Hao, Kun-Peng Huang, Jin-Li, Qing-Fang Shang

“…The results show that under the premise of keeping the fluidity constant, the strength of the ITP slurry increases with the increase of the curing agent content; At the same strength, the water consumption significantly affects the fluidity; When using 8%~16% different curing agent dosage, the expansion degree is 280 mm ~ 600 mm, the wet density is 1.9 g/cm3 ~ 2.1 g/cm3, the 28d strength after curing is 1.4 MPa ~ 3.7 MPa, and the stone rate is greater than 92%; The ITP slurry prepared by vibration mixing with a mixing time of 120 s and the amount of curing agent at 8% meets the engineering application requirements of 7d strength of 0.6 MPa and expansion of 250 mm. The research shows that the iron tailings powder slurry prepared by vibration mixing has high strength after solidification, and it is a new way of resource utilization of iron tailings powder with large consumption and good economy to be used for goaf backfilling.…”
