Simplot Vernal Phosphate Mine, Utah

The phosphate ore mined here, north of Vernal, Utah, goes to the JR Simplot Rock Springs Wyoming Plant via a pressurized slurry pipeline 96 miles long. The mine was originally developed by the San Francisco Chemical Company in 1960. It was purchased by Chevron in 1981, which built the slurry pipeline and the Rock Springs plant around 1985.
