Magnetite
Magnetite, as is implied by its name, is magnetic. It will attract a magnet but does not act as a magnet itself. Naturally magnetized magnetite, called a lodestone, will act as a magnet, and was used for the first compasses. ... The mine operated continuously until 1966, with over 130 years of ore production.

In many iron ore mines, wet high-intensity magnetic separation is being preferred in the concentration of low-grade hematite ores to avoid the flotation methods. The other important factor is the selection of magnetic separator which can capture the hydroxyl-bearing iron minerals such as goethite and limonite that are feebly magnetic.
