The Mineville district produced two distinct varieties of iron ore (Birkinbine 1890): magnetite-apatite and magnetite-silicate ore. The magnetite-apatite ore was produced from what was called the "Old Bed" and the magnetite-silicate ore came from the "New Bed". These names were applied to the ore mined from different mining works.
