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.

第一台用于钛铁矿分离的全尺寸 cHGMS 分离器


我们之前对离心式高梯度磁分离 （cHGMS） 的研究已完全证实其提高 HGMS 工艺分离选择性的有效性，但它们仅限于中试规模的研究。在这项工作中，第一台全尺寸 CenMag-300 cHGMS 分离器用于清洁原生钛铁矿精矿，该精矿是通过脉动 HGMS （PHGMS） 粗加工工艺生产的。分离结果表明，在 TiO2 回收率达到 81.07% 时，它能够将 TiO2 品位从进料中的 15.25 % 提高到精矿中的 32.49 %，远优于循环 SLon-100 PHGMS 分离器。这项研究的结果证实了 cHGMS 技术在工业运行中的可行性。
