Three-dimensional flotation of fine particles. This project aims to research three-dimensional flotation of fine particles under both batch and continuous steady state conditions. In flotation, fine hydrophobic particles adhere to the two-dimensional surface of rising air bubbles, forming concentrate. In three-dimensional flotation, however, the particles adhere to and become embedded in a novel binder, forming a highly buoyant product. The process is very selective and arguably 1000 times faster than conventional flotation. The project is expected to provide the knowledge required to achieve scale-up, so the technology can be used to recover high value product from tailings waste, eliminating the capital impediment and possibly transforming the entire mining industry.

微细颗粒的三维浮选。本项目旨在研究细粒物料在间歇和连续稳态条件下的三维浮选。在浮选中，细小的疏水颗粒粘附在上升气泡的二维表面上，形成精矿。然而，在三维浮选中，颗粒粘附并嵌入新型粘合剂中，形成高度漂浮的产品。这个过程是非常有选择性的，可以说比传统的浮选快1000倍。该项目预计将提供实现规模扩大所需的知识，因此该技术可用于从尾矿废物中回收高价值产品，消除资本障碍，并可能改变整个采矿业。
