U.S Geological Report Summary of Use of Recycled Tungsten in 2000
This report,which is one of a series reports on metal recycling ,defines and qualifies the flow of tungsten-bearing materials in the United States from imports and stock releases through consumption and disposition in 2000,with particular emphasis on the recycling of industrial scrap (new scrap) and used products (old scrap).Because of tungsten’s many diverse uses, numerous types of scrap are available for recycling by a wide variety of processes. In 2000,an estimated 46 percent of U.S tungsten supply was derived from scrap. The ratio of tungsten consumed from new scrap to that consumed from old scrap was estimated to be 20:80. Of all the tungsten in old scrap available for recycling, an estimated 66 percent was either consumed in the United States or exported to by recycled. |
