Abstract The transition from a carbon to a metals-based economy is creating an unprecedented demand for minerals, and in turn a diabolical process engineering challenge, given the decreasing grade of the accessible ore, the need to address new and more complex mineralogy, while reducing the environmental footprint. This challenge demands transformational change to the practice of minerals processing, including the need for process intensification. This paper examines recent developments associated with the Reflux Classifier to illustrate how it is possible to achieve significant improvement in separation efficiency, with a significant increase in processing “speed”. Here, it is necessary to control the forces that act on the particles in new ways to enhance the selectivity and ultimately the segregation of the valuable particles from the gangue. The paper explores the application of forces that exploit differences in particle density and differences in surface properties within a hydrodynamic medium such as water.

精细矿物分离的过程强化

摘要 由于可获取矿石的品位不断下降，需要解决新的和更复杂的矿物学问题，同时减少对矿物的需求，从碳经济向金属经济的转变正在创造对矿物的前所未有的需求，反过来又是一个严峻的过程工程挑战。环境足迹。这一挑战要求对矿物加工实践进行转型变革，包括对工艺集约化的需求。本文考察了与回流分级器相关的最新发展，以说明如何显着提高分离效率，同时显着提高处理“速度”。在这里，有必要以新的方式控制作用在颗粒上的力，以提高选择性并最终将有价值的颗粒从脉石中分离出来。
