摘　　要：洁净煤技术是煤炭可持续性利用的关键因素,其要求矿物在研磨过程中时,选取有效的选煤方法。目前,国内外超细颗粒的选煤技术主要分为物理分离法(包括重力分离法、磁分离法和静电分离法)和物理化学分离法(包括油团聚法和泡沫浮选法)。基于此,对目前超细颗粒的选煤技术的发展进行了综述,并对超细煤粒筛选过程中存在的问题进行了分析。Clean coal technology is a key factor for the sustainable utilization of coal,which requires more effective coal preparation methods during the grinding process of minerals.In this paper,a comprehensive literature review of ultra-fine coal particle beneficiation technology is carried out,and the main ultra-fine coal particle beneficiation technologies at home and abroad are summarized.At present,ultrafine coal particle beneficiation technologies at home and abroad are divided into physical separation methods(including gravity separation method,magnetic separation method and electrostatic separation method)and physical and chemical separation methods(including oil agglomeration method and bubble flotation method).This paper summarizes the current development of ultrafine coal powder beneficiation technology,and analyzes the problems existing in the ultrafine coal particle beneficiation process.
