Once prepared, the mine site is cleared of workers and equipment, and the blast is detonated. Each of the holes is detonated just a millisecond apart, resulting in a pile of crude iron ore that is broken apart to a minus 2 m x 2 m size. The wide holes in the ground created by drilling, blasting, and ore removal are referred to as 'open pits'.

Steel used in munitions and equipment was largely made possible by ore mined in northern Minnesota. More than 800 million tons of iron ore have been shipped from the Hull Rust Mahoning complex. At peak production in the 1940s, as much as one-quarter of the ore mined in the U.S. came from the Hull Rust pit.

On a world scale, the quantities produced are low. Since the iron ore is extracted in underground mines (Fig. 2), mining costs are hardly competitive compared to the open pit mines of, for example, Australia or Brazil. As a consequence, the low iron ore prices have been very problematic for mining companies.
