By applying ultrafine grinding-magnetic flocculation separation (MFS) to the raw ore (29.85% Fe), a concentrate assaying 74.12% Fe with 81.45% iron recovery was obtained. The iron recovery increased by 6.68% compared with the conventional magnetic separation (CMS).

Fig 3 Types of processing ores. The wet processing (Fig 4) is normally practiced for low / medium grade (60 % Fe to 63 % Fe) hematite iron ore. The wet process consists of multi-stage crushing followed by different stages of washing in the form of scrubbing and / or screening, and classification etc., but the advantage is only partial removal of adhered …

The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very fast, the focus is on the beneficiation of low-grade resources. However, most of these ores do not respond well to the conventional …

The relevance of the paper is that dry magnetic separation (DMS) is the main beneficiation method of magnetite ores. The lack of efficient industrial-grade machines and apparatus for separating fine-grained magnetite ores means that DMS is used mainly as a pre-concentration operation for fairly large classes.
