The mill was built in 1908 and was the largest tungsten mill in the world at the time. Demand for tungsten during World War I created a mining boom. Hundreds of prospectors swarmed the areas around Nederland looking for tungsten deposits. By 1917 demand for tungsten produced in the United States had slowed, and Nederland's tungsten activity came to a halt. The Primos Chemical Company concentrating plant was torn down sometime during the 1920s.Rights management statement available at: http://library.mines.edu/digital/rights.htmlTungsten ore processing plantsStillImage
