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.
an example metal mine might spend $5.00/t of ore on electricity; an equivalent amount on grinding media in the SAG circuit alone; but only $0.30/t of broken ore on explosives at the drill and blast stage. Yet, the blasting process is a much more energy efficient method of fragmenting rock. The need for energy efficient processing is
