Abstract

Magnetite is the core of the steel industry and a pillar of economic development in resource-based regions. Low-intensity magnetic separation (LIMS) is a highly effective method for separating magnetite. However, studies on LIMS mechanism and the optimization and development of equipment have progressed slowly due to high complexity of the magnetization mechanism of magnetic ore particles during the separation process, the ambiguity of the interaction mechanism between multi-physical fields and mineral particles, and the lack of characterization and observation methods in the dynamic separation process. Recently, advancements in numerical simulation have significantly contributed to studies on prediction of separation results in dry and wet low-intensity magnetic separation, equipment optimization and development, interaction mechanisms between multi-physical fields and mineral particles in the dynamic separation process, and the interaction mechanisms between mineral particles. These studies outline the problems that constrain the application of numerical simulations in LIMS, and proposes the future research directions of numerical simulation technology in the field of weak magnetic separation.

数值模拟在提高弱磁选机效率中的研究进展及应用

磁铁矿是钢铁产业的核心，是资源型地区经济发展的支柱。弱磁选是一种高效的磁铁矿分离方法。然而，由于磁性矿粒在分选过程中磁化机理的高度复杂性、多物理场与矿粒相互作用机理的模糊性以及动态分选过程中缺乏表征和观察方法等原因，对LIMS机理的研究和设备的优化开发进展缓慢。近年来，数值模拟技术的进步对干湿弱磁选分离结果预测、设备优化与开发、多物理场与矿粒在动态分离过程中的相互作用机理、矿粒之间的相互作用机理等方面的研究做出了重要贡献。这些研究概述了制约数值模拟在弱磁分离领域应用的问题，并提出了数值模拟技术在弱磁分离领域的未来研究方向。
