Magnetite resembles a number of other metal ores, but it is the only common mineral that exhibits magnetism. So magnetism alone is sufficient to distinguish relatively pure magnetite samples. It is more difficult to distinguish cases where magnetite is mixed with other dark colored minerals, such as hematite and ilmenite. ...
magnetite, finding magnetite is not as electrochemically responsive as the common sulphides and graphite. Vanhala and Peltoniemi (1992), in a spectral IP field study, showed magnetite tended to have a lower, but still finite, IP response than sulphides. Malmqvist, in a field study of a small, low
