Thus, magnetic separation under dry process is prospective as an alternative method [3]. In this paper, we developed high gradient magnetic separation (HGMS) system under dry process. In dry HGMS system, powder coagulation caused by particle interaction is not negligible. Powder coagulation causes a blockage of magnetic …

Through the combined treatment of magnetization roasting and magnetic separation, hematite (Fe 2 O 3) is roasted in a reducing atmosphere at a certain temperature, and hematite is transformed into magnetite (Fe 3 O 4). The magnetism is greatly enhanced, which is easy to be separated by low-intensity magnetic separators. …

The optimum grade that could be obtained from single-stage dry magnetic separation was 35.52% Mn, and with a Mn:Fe ratio of 1.77, and 44% Mn recovery in the case of sample 1; whereas, a 33.75% Mn grade, with a Mn:Fe ratio of 1.66 at Mn recovery of 44% was reported for Sample 2. It was observed that both samples had a similar input chemistry ...

2.1. Decription on DHIDMS separator. A DHIDMS separaor produces a large magnetic field intensity and gradient on the drum surface; thus, it is applicable for the separation of weakly magnetic ores and for the purification of non-metallic ores. As shown in Fig. 1, a pilot-scale DHIDMS separator is mainly composed of vibrating feeder, …
