Coleman Quartz Inc.: Novaculite For The Ferrosilicon Industry

Coleman Quartz Inc. has a long history as the sole U.S. producer of lascas for the cultured quartz growing industry based on its unique deposits in Arkansas. Since 1989 the company has also been producing metallurgical grade silica for the ferrosilicon industry from a deposit of unusually pure Arkansas novaculite. This paper chronicles Coleman's trans-formation of an abandoned railroad ballast quarry into a generator of $1.5 million in annual sales to a nontraditional novaculite market. Potential additional applications for this high quality silica rock will also be mentioned.
