Hematite is the principle ore of iron. Huge quantities are mined throughout the world for industrial production. It is the source for roughly 90 percent of all iron mined in the United States. Hematite was largely used in the past as a red and brown pigment, although nowadays cheaper sources have been substituted.

Hematite ore of particle size 4000 microns is to be ground dry to 200 microns (P 80). The work index of the ore was determined and found to be equal to 15.1 kWh/t. Balls of diameter 110 mm were added as the grinding media. The mill was rotated at 68 % of the critical speed and expected to produce at the rate of 12 t/h.

The hematite is red to black, oolitic to massive, earthy to hard. It was associated with goethite and an array of phosphate minerals (Chamberlain, 1877, Hawley and Beavens, 1934; U.S.G.S., 1976; Paull, 1977). It was mined along Iron Ridge near Mayville in Sec. 12 and 13 T.11N R.16E until the mid-1970's. Beds up to 55 feet thick occurred.
