Ion flotation has delivered remarkable separations via high selectivity, recovery and concentration upgrade. Yet, the technology has not provided solutions that are economically viable. This new project, however, aims to deliver the paradigm shift required in the flotation hydrodynamics to finally permit ion flotation to be applied to a broad range of industrial problems. Specifically, the aim is to increase extraction rates by more than an order of magnitude by dramatically increasing bubble-liquid segregation rates, and bubble-surface fluxes. In turn the project is expected to develop a new line of solutions to industrial problems in hydrometallurgy for recovering precious metals and for solving toxic environmental problems.

离子浮选通过高选择性、高回收率和高浓缩度实现了显著的分离。然而，该技术并没有提供经济上可行的解决方案。然而，这个新项目的目的是提供浮选流体力学所需的范式转变，最终允许离子浮选应用于广泛的工业问题。具体而言，其目的是通过显著增加气泡-液体分离速率和气泡表面通量来将提取速率增加一个数量级以上。反过来，该项目预计将开发一系列新的解决方案，以解决湿法冶金中回收贵金属和解决有毒环境问题的工业问题。
