Magnetic Separation of Pyrite - 911metallurgist

2021-2-8 · The inherent susceptibilities of coals (about minus 0.5 x 10 -6) and of pyrite (0.3 x 10 -6) do not permit an effective separation of pyrite in a large-scale operation. Present experiments indicate that an effective susceptibility >3 x 10 -6 for pyrite would be sufficient.
