mining for magnetic minerals

Locations of Deposits - Massachusetts Institute of Technology

In the early period of mining REEs, they were mined primarily from placer deposits, which are mineral accumulations in rivers and on beaches. Placer deposits form when minerals are separated by density as lighter minerals remain suspended and more dense minerals are deposited along the riverbed.

Magnetite - Wikipedia

Magnetite is a rock mineral and one of the main iron ores, with the chemical formula Fe 3 O 4.It is one of the oxides of iron, and is ferrimagnetic; it is attracted to a magnet and can be magnetized to become a permanent magnet itself. It is the most magnetic of all the naturally-occurring minerals on Earth. Naturally-magnetized pieces of magnetite, called lodestone, will attract small pieces ...
