Iron Ore Processing, General
For taconite iron ores, mining iron ore begins at ground level. Taconite is identi - ed by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28% iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.
