The plant closed in 1946 when the demand for vanadium declined, but it was re-opened in 1948 by the Atomic Energy Commission to process carnotite ore for uranium. This was done by salt roasting crushed ore and then leaching and precipitating the uranium concentrate (yellow cake) and vanadium concentrate (red cake).Rights management statement available at: http://library.mines.edu/digital/rights.htmlOre-dressing plantsStillImage
