Brown hematite, magnetite, and titaniferous magnetite ores have been mined and smelted, but in later years the titaniferous ores have been completely neglected because they are not adapted to modern blast-furnace practice. Until within a few years the magnetite de posits furnished nearly all the ore mined, but recently the brown ores.
