Potash at Wendover is produced primarily from brine containing salt, potash and magnesium chloride that is collected in ditches from the shallow aquifers of the West Desert. These materials are also collected from a deeper aquifer by means of deep brine wells.

Brine from a shallow potash containing aquifer is collected in over 100 lineal miles of open ditches throughout the 88,000 acres of land controlled by Intrepid. In addition to the brine that is collected in the shallow aquifer, there is a deep potash containing aquifer 1,000 feet below ground.

The Wendover facility has a current estimated productive capacity of approximately 100,000 tons of potash annually; evaporation rates have historically resulted in actual production between approximately 65,000 and 100,000 tons of potash.

Pump the brine collected in the ditch system into an 8,000 acre solar evaporation pond to evaporate water and precipitate salts. Over five billion gallons of brine are pumped into the solar pond system each year. As the brine becomes saturated with potash, it is transferred through a series of smaller evaporation ponds into harvest ponds. When the ripened brine finally reaches the harvest ponds, the ore (a combination of salt and potash) precipitates onto the pond floor. The remaining brine in the harvest ponds is removed and the ore is harvested and transported by elevating scrapers to the mill for processing. In the mill, the potash is separated from the salt by flotation. The material is then dried, compacted, and screened into standard product or compacted into a granular grade of white potash.
