Pilot plant study of dry deposition of paste tailings in Baogang West Mine

In order to understand the deposition of paste tailings, laboratory and pilot plant tests were conducted on iron ore tailings from Baogang Baiyun E’Bo West Mine. Relevant experiments include those of tailings rheology, pilot plant thickening, flume and consolidation, the stimulation of the properties of dust suppression and flood scouring resistance, and so on. The study reveals the technical feasibility of the dry-type deposition of high density or paste iron ore tailings from Baogang Baiyun E’Bo West Mine. The existing thickening techniques can produce the required concentration of tailings for paste deposition. It also shows that after being discharged into the tailings disposal site, the tailings will present desirable behaviours of consolidation, dust suppression and flood scouring resistance.
