摘要

摘要:
在高梯度磁选分离过程中存在机械夹带、磁性夹带、竞争捕获等现象，最终导致选择性差、分选腔堵塞、分选效率低等一系列问题。目前科研工作者针对高梯度磁选的理论研究主要集中于对颗粒受力分析并力的大小计算、颗粒轨迹模型和颗粒堆积模型的构建、聚磁介质的研发与优化。以颗粒受力为基础，通过颗粒的堆积模型和轨迹模型分析造成选择性差以及效率低的原因，综述聚磁介质的研发与优化，旨在为高梯度磁选技术在工业应用中的优化与理论研究提供参考，并对高梯度磁选技术理论研究的未来趋势进行展望。

Abstract:
Mechanical entrainment, magnetic entrainment and competitive capture occur in the separation process of high gradient magnetic separation, ultimately leading to a number of problems such as poor selectivity, clogging of the sorting chamber and low sorting efficiency. At present, the theoretical study of high gradient magnetic separation mainly focuses on particle force analysis and calculation, the construction of particle trajectory model and particle stacking model, and the research and development and optimisation of polymagnetic media. Based on the particle force, this paper analyses the causes of poor selectivity as well as low efficiency through the particle stacking model and trajectory model, and reviews the development and optimization of matrix, aiming to provide a reference for the optimization and theoretical research of high-gradient magnetic separation technology in industrial applications, as well as looking forward to the future trend of theoretical research of high-gradient magnetic separation technology.
