摘要

我们之前对离心高梯度磁分离（cHGMS）的研究已经充分证实了它对提高HGMS过程的分离选择性的有效性，但这些研究都局限于中试规模的研究。在这项工作中，第一台全尺寸的CenMag-300 cHGMS分离器被用于清洗由脉动HGMS （PHGMS）粗选工艺生产的初级钛铁矿精矿。分离结果表明，该浮选机可将TiO2品位从进料的15.25%提高到精矿的32.49%，TiO2回收率达到81.07%，明显优于循环SLon-100 PHGMS分离机。这次调查的结果证实了cHGMS技术用于工业操作的可行性。

First full-scale cHGMS separator for separation of ilmenite

Our previous research on centrifugal high gradient magnetic separation (cHGMS) has fully confirmed its effectiveness to improve the separation selectivity of HGMS process, but they were confined in pilot-scale investigations. In this work, the first full-scale CenMag-300 cHGMS separator was used to clean a primary ilmenite concentrate, which was produced from a pulsating HGMS (PHGMS) roughing process. The separation results demonstrated that it was able to improve the TiO₂ grade from 15.25 % in feed to 32.49 % in concentrate at TiO₂ recovery reaching 81.07 %, which is much superior to that of cyclic SLon-100 PHGMS separator. The outcome from this investigation confirmed the feasibility of cHGMS technology for industrial operation.

期刊介绍： The purpose of the journal is to provide for the rapid publication of topical papers featuring the latest developments in the allied fields of mineral processing and extractive metallurgy. Its wide ranging coverage of research and practical (operating) topics includes physical separation methods, such as comminution, flotation concentration and dewatering, chemical methods such as bio-, hydro-, and electro-metallurgy, analytical techniques, process control, simulation and instrumentation, and mineralogical aspects of processing. Environmental issues, particularly those pertaining to sustainable development, will also be strongly covered.
