POTASSIUM SULPHATE
[EIRI/EDPR/1574] J.C.369
INTRODUCTION
Potassium sulfate (K2SO4) mineral name arcanite forms colorless, nonhygroscopic 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.
