1. Introduction. In arid and severely cold regions such as west China, a plenty of iron ores are difficult to be economically utilized due to water scarcity [1, 2], so that the utilization for such iron ores has an urgent demand for high-efficient dry magnetic separation (DMS) technology [[3], [4], [5], [6]].A large portion of iron ores were currently …
The attraction of magnetite to iron was discovered in China as early as 300 BC during the Warring States Period (476–221 BC). In the eleventh century, Shen Kuo (1031–1095) of the Northern Song Dynasty (1127–1279) of China, using the magnetism of a magnet (the presence of two magnetic poles), invented the nautical compass (one of …
As the primary beneficiation method for iron ore, magnetic separation improves ore grade, reduces silica and harmful impurity content, and facilitates the smelting process [28], [32], [33]. Utilizing magnetic separation is an important step towards achieving green and low-carbon steel production.
