POTASSIUM SULPHATE (Cap: 200 TPD)

  Potassium sulfate (K2SO4) mineral name arcanite forms colorless, no hygroscopic crystal. It occasionally occurs in nature in the pure state in salt deposit, but is more widely found in the form of mineral double salts in  combination  with sulfates of calcium, magnesium, and sodium.

Potassium sulfate is after potassium chloride the most important potassium containing fertilizer being used mainly for special crops. Potassium sulfate constitutes 5%  of  the  world demand for potash fertilizer.

Prior to 1939, the German potash industry  was  the  chief source of potassium sulfate for American chemical and  fertilizer industries, although considerable tonnages were being produced in this  country  by  the  interaction  of potassium chloride and sulfuric acid as a side product of salt-cake  manufacture.  With the termination of European imports, the production of the salt was undertaken on a larger scale by the American Potash and Chemical Corp.  through the interaction of burkeite  (Na2CO3 2Na2SO4)  with  potassium  chloride  followed  in  turn  by   the successful  recovery  of  this  salt  from  langbeinite  by   the International  Minerals  and Chemical Corp. In  agricultural  use potassium  sulfate  is  preferred for the  tobacco  crop  of  the Southeast and the citrus crop of Southern California.

Relatively small amounts of other potassium salts are used as fertiliser, generally for special purposes. Tobacco and some vegetables are adversely affected by high chloride concentration, and K2SO4 or KNO3 are preferred. K2SO4 is made  in  substantial quantities  in  Europe by the Mannheim process  from  potash  and H2SO4 and in the united states and other countries  by  various exchange reacting between K, Na, and Mg salts.
