Gradins of M i c a A. N E W and more efficient process for sorting small flake mica, an essential in gredient in much of the electrical equip ment being manufactured for the Nation's armed forces, has been developed by Bureau of Mines engineers and is available to commercial producers. The method alreadj'· has produced test batches of closely graded mica flakes which were used by a large commercial manufacturer of •electrical equipment in producing radio parts. The process is known as electro static grading. Details are explained in Report of In vestigations 3662, *'Lamellar Grading of Powdered Mica", by Oh ver Ο. Ralston and Foster Fraas which may be obtained free of charge from the Bureau of Mines, Department of the Interior, Washington, D . C.
