Magnetic Separation

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 …
