After many years of hard work, a process was developed to create taconite pellets. Taconite saved Minnesota''s iron ore mining industry. To make these pellets, the hard taconite ore is blasted and then ground down with water to a fine powder. The fine iron rich particles, mostly of magnetite are extracted from the powder by use of magnetism.

"A taconite plant may have as many as 18 rod mills with one rod alone weighing as much as 500 Ib (227 kg). Tumbling around in the mills with the hard taconite wears away the rods and balls and need to be replaced frequently." This is a costly and energyintensive process and the waste rods and balls are a disposal problem, according to NRRI.
