This project aims to improve the dewatering behaviour of waste tailings from mineral processing activites. Dewatering and disposal of tailings containing fine particles are serious issues which confront the mineral industry. Effective dewatering of tailings is determined by particle-solution interfacial chemistry and particle interactions. These properties will be manipulated by matching the molecular architecture and functionality of flocculants to mineral particle surface chemistry. Optimization of tails interfacial chemistry and particle interactions through conventional and non-conventional flocculants will be investigated and electoosmosis will be applied to achieve maximum dewatering behaviour.The scientific and environmental outcomes will be beneficial to all stakeholders.

该项目旨在改善选矿活动中废尾矿的脱水性能。含有细颗粒的尾矿的脱水和处理是采矿业面临的严重问题。尾矿的有效脱水取决于颗粒-溶液界面化学和颗粒相互作用。这些特性将通过将絮凝剂的分子结构和功能与矿物颗粒表面化学相匹配来控制。将研究通过传统和非常规絮凝剂优化尾矿界面化学和颗粒相互作用，并应用电渗透以实现最大程度的脱水行为。科学和环境成果将使所有利益相关者受益。
