Mining Iron Ore Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.

Mar 30, 2016· The mine's original grinding circuit consisted of ball mills exclusively. The primary stage comprised 5 ball mills, the secondary stage 3 ball mills, and the final, tertiary stage 2 ball mills. The original tertiary grinding fineness was -325 mesh with 71-73% passing. Iron concentrate grade was 65% and the average recovery rate 87%.
