Mine, mill, and smelter wastes as barren piles on the landscape are considered pollutants. The fine minerals in such wastes that become airborne may cause air and water pollution. The Bureau of Mines is investigating methods of mitigating such pollution by devising means for stabilizing mineral industry wastes. Physical, chemical, vegetative, and combination methods of stabilizing fine wastes have been developed. Since vegetation offers the advantages of renewability and improved appearance, major research emphasis has been directed toward developing vegetative and combined chemical- vegetative stabilization procedures. A resinous adhesive compound used in conjunction with selected vegetation appears exceptionally effective for achieving stabilization of many mill tailings. Treatment of a 10-acre plot of typical copper mill tailings by the combination method effectively stabilized the fine sands against wind erosion.
