“EcoFlot. Scale-up and Demonstration of the CoarseAir Flotation Technology - Froth flotation is the most widely used separation technology for separating different minerals from one another in order to increase the grade (purity) of mineral ores and to produce a concentrate. The grade of the metal of the metal in this concentrate must be high enough that the material can be economically smelted in order to produce the metal. A significant challenge with froth flotation is that ore particles need to be ground very fine for current flotation cell designs to work optimally. The energy required for this grinding is typically the biggest single energy cost in mining and minerals processing, thus representing both a significant economic and environmental cost. If flotation could be done at coarser particle sizes it would therefore result in significant energy savings. The aim of this project is therefore to support the development of a novel coarse particle flotation cell design from a lab scale test unit to full industrial scale application.This project has a number of academic and industrial partner organisations working on various aspects, but the contribution of Imperial College to this project will be through the modelling and simulation of these cells. In the first stage of the project we will use data from the lab scale cell to improve and extend the simulation software that we have develop for fluid flow and associated particle transport, as well as to validate the simulator’s performance. As the models that we will be using are directly based on the physics of these systems, confidence gained in the simulator’s ability to model the lab scale unit will translate into confidence in the simulator’s ability to predict the performance of pilot and, ultimately, full scale versions of this novel cell.This simulator will then allow us to evaluate the performance of different design modifications and associated operating conditions without the need for expensive fabrication and experimental testing. This will mean that only the most promising designs and sets of operating conditions will need to be experimentally tested, saving both costs and time. The results from these tests, together with any discrepancies observed between the predicted and actual performance will allow us to further improve our simulator’s performance, especially as we increase the scale of the machines being designed and tested from the pilot scale up to commercial scale units.”

“EcoFlot。粗粒空气浮选技术的放大和示范-泡沫浮选是最广泛使用的分离技术，用于将不同矿物相互分离，以提高矿石的品位（纯度）并生产精矿。该精矿中的金属的金属品位必须足够高，使得材料可以经济地熔炼以生产金属。泡沫浮选的一个重大挑战是，矿石颗粒需要被研磨得非常细，以使当前的浮选槽设计最佳地工作。这种研磨所需的能量通常是采矿和矿物加工中最大的单一能量成本，因此代表了显著的经济和环境成本。如果浮选可以在较粗的颗粒尺寸下进行，则将因此导致显著的能量节省。因此，该项目的目的是支持开发一种新型的粗颗粒浮选槽设计，从实验室规模的测试单元到完全的工业规模应用。该项目有许多学术和工业合作伙伴组织在各个方面开展工作，但帝国理工学院对该项目的贡献将是通过这些槽的建模和模拟。在该项目的第一阶段，我们将使用实验室规模的细胞的数据，以改善和扩展我们已经开发的流体流动和相关的颗粒传输的模拟软件，以及验证模拟器的性能。由于我们将使用的模型直接基于这些系统的物理特性，因此对模拟器模拟实验室规模单元的能力的信心将转化为对模拟器预测飞行员性能的能力的信心，最终，该模拟器将允许我们评估不同设计修改和相关操作条件的性能，需要昂贵的制造和实验测试。这意味着只有最有前途的设计和操作条件集需要进行实验测试，从而节省成本和时间。这些测试的结果，以及预测性能和实际性能之间观察到的任何差异，将使我们能够进一步提高模拟器的性能，特别是当我们将设计和测试的机器规模从中试规模增加到商业规模时。”
