Dry Milling Corn The dry milling process requires the miller to remove the corn hull and germ without reducing the endosperm. The dry milling and alkaline cooking industries processed about 161 million bushels of corn in 1986. Total corn usage has ranged from a low of 154 million bushels in 1975 to a high of 170 million bushels in 1982 (table ...

Radiation Facts. Regardless of how uranium is removed from rock, the extraction process creates radioactive wastes. If not managed properly, mining waste and mill tailings can contaminate the environment. Uranium is a naturallyoccurring radioactive element that has been mined and used for its chemical properties for more than a thousand years.

The Milling Process UK Flour Millers. The flour milling process has evolved from wheat being ground between two large stone wheels (although this process does still occur in a few mills). In a roller mill the practice centres around separating the three components of a wheat seed the white endosperm, the outer bran layers and the wheat germ. [PDF]
