煤系矿物的表面磁性强化是利用通常磁选设备实现高硫煤脱硫脱灰的新型关键技术。本文着重对热处理、选择性磁罩盖、氧化或还原、微波辐照预处理以及表面磁性的溶液电化学调整等方法和煤脱硫作用原理进行了综述和探讨。
Magnetic strengthening of the surface of coal-based minerals is the use of the usual magnetic separation equipment to achieve high-sulfur coal desulfurization deashing a new key technology. This article focuses on the heat treatment, selective magnetic cover, oxidation or reduction, microwave irradiation pretreatment and surface magnetic solution electrochemical adjustment methods and the principle of coal desulfurization were reviewed and discussed.
