Tellurium occurs chiefly as telluride in gold, silver, copper, lead, and nickel ores in Colorado. California, Ontario, Mexico, and Peru, and infrequently as free tellurium and tellurite (tellurium dioxide, Te02) The anode mud from copper and lead refineries, or the flue dust from roasting telluride gold ores is treated by fusion with sodium nitrate and carbonate and the melt extracted with water. The resulting solution is acidified carefully with H2S04, whereupon tellurium dioxide is precipitated, and die dioxide reduced to free tellurium by heating with carbon. 

In the southwest corner of Colorado at the edge of the high desert, Durango is conveniently located near a myriad desert recreation opportunities. Four Corners National Monument, Mesa Verde National Park, the Anasazi cliff dwellings and Navajo Country are all nearby. Although Durango lies in the desert, the Rockies are not far. Some of Colorado s most remote and desirable ski resorts, such as Purgatory and Telluride, are within a two hour drive.
