Taconite is a lowgrade iron ore. When the highgrade natural iron ore was plentiful, taconite was considered a waste rock and not used. But as the supply of highgrade natural ore decreased, industry began to view taconite as a resource. Dr. Davis of the University of Minnesota, along with other scientists and engineers, conducted years ...

PDF Blasting for Improved Autogenous Milling at Hibbing Taconite Company

Hibbing Taconite Company (Hibtac) has a long history of also specifying a maximum powder factor (lbs. of powder per long ton of rock) used in blast design. Fully autogenous (AG) mills require feed which includes a percentage of coarse sizes. Early research pointed to an optimum feed of 40% minus 3inch, 20% 3 to 6inch and 40% 6 to 10inch rock.

The rod and ball mills are also in closed circuit with classification systems such as cyclones. An alternative to crushing is to feed some coarse ores directly to wet or dry semiautogenous or autogenous grinding mills (using larger pieces of the ore to grind/mill the smaller pieces), then to pebble or ball mills.

"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.
