中文摘要
翻译
超细尾矿处理后,固含量低,保水率高,长期抗剪强度几乎为零。如果不进行处理,尾矿在尾矿库中数十年处于流体状态,降低了水循环效率,对环境产生影响,造成矿山关闭延迟。目前UFT的脱水主要依靠自重固结。现有的脱水技术,如化学添加剂、真空过滤和预压固结,在大规模的现场应用中表现出有限的成功。拟议的研究将解决采矿工业在处理和回收矿山尾矿方面面临的挑战。
英文摘要
Ultrafine tailings (UFT) have low solid content, high water retention and virtually zero shear strength over long period after disposal. Without treatment, the tailings remain in a fluid state in tailings ponds for decades, reducing efficiency of water recycle, generating environmental impacts and causing delays in mine closure.Currently dewatering of UFT is mainly relying on self-weight consolidation. Existing dewatering technologies, such as chemical additives, vacuum filtration and preloading consolidation, have shown limited success in large scale field applications. The proposed research will address challenges facing the mining industry on disposal and reclamation of mine tailings.
