Sulfate of potash

Occurrence. Muriate of potash [7447 0-7] KCl, and sulfate of potash [7778-80-5] K2SO4, are produced from brines in the United States... 

Three brine potash operations are located in Utah at Moab, Ogden, and Wendover and one in California at Seades Lake. Operations in Seades Lake produce both mudate and sulfate of potash. The Ogden operation produces sulfate of potash. The others produce muriate. 

Domestic potash production suppHes one-third of U.S. consumption. The rest comes from mines in Canada and Europe. Pnces of both KCl and K2SO4 fluctuate. KCl ranges between 65 to 95 dollars per ton. Sulfate of potash sells for 150 to 190 dollars per ton. 

Sulfates. Potassium sulfate. [CAS 7778-80-5], sulfate of potash, K2.SO4, white solid, soluble. Common constituent of potassium salt minerals. Used (l)as an important potassium fertilizer, (2) in the preparation of potassium or potash alums potassium hydrogen sulfate, KHSO4, white solid, soluble potassium pyrosulfate. K2S2O7, white solid, soluble, formed by heating potassium hydrogen sulfate to complete loss ot H2O. See also Fertilizer. 

The term potash generally refers to potassium chloride, but it is also used to designate other potassium compounds that may be qualified by the words muriate of potash, sulfate of potash, etc. 

The name potash derives from an early production method in which potassium carbonate, leached from wood ashes, was crystallized by evaporating the leachate in large iron pots. The salt potassium chloride (muriate of potash or KC1) is now the major source of the element (95%) other important salts are potassium sulfate (sulfate of potash, K2S04), potassium magnesium sulfates of varying K/Mg ratios, and potassium nitrate (KN03). 

Sulfate of potash (K2S04), unlike the earlier-discussed potash salts, does not occur as natural deposits. It can be recovered by fractional crystallization from such natural brines as those of the Great Salt Lake in Utah and Searles Lake in California. Here separation and recovery are achieved by solar evaporation in shallow ponds. These processes can be utilized only where a suitable brine source is available, and where solar evaporation rates are high.

Potassium is also found in bat guano, seabird guano, kelp, and sulfate of potash.
