Conversion of phosphogypsum to potassium sulfate: Part I. The effect of temperature on the solubility of calcium sulfate in concentrated aqueous chloride solutions
Potassium sulfate (in British English potassium sulphate (SOP), also called sulphate of potash, arcanite, or archaically known as potash of sulfur) is the inorganic compound with formula K 2 SO 4. It is a white water soluble solid.
Potassium sulfate is used in the manufacture of gypsum cements, fertilizers, alums, and potassium glass. In a closed environment, a saturated solution of potassium sulfate will form an equilibrium at a relative humidity of about 97% (20C).

Calcium sulfate (gypsum) contains 1518 percent sulfur. It is found in ordinary superphosphate and is a byproduct of manufacturing concentrated superphosphate. Gypsum is an effective sulfur source, but not popular as a sulfur fertilizer because of the low sulfur content.
Potassium Sulfate 0050 is used to supply potassium to the soil. We have a potassium sulfate that is approved for organics and we have one whose binding agent is not approved, but the product is a very clean natural product from the earth.
USES: Potassium sulfate is used for analytical chemistry, gypsum cements, fertilizers, glass and aluminum manufacture, and pyrotechnics. HANDLING: Avoid ingestion or inhalation, but not poisonous or hazardous. Store in a cool, dry place.
The present invention relates to a process for the manufacture of monopotassium phosphate of a high purity without utilizing organic solvents. According to the process, monopotassium sulfate is reacted, at a temperature in the range of between 40 to 100 degrees with a phosphate constituent selected from phosphate rock, dicalcium phosphate or mixtures thereof in the presence of phosphoric acid.

It''s calcium sulfate and is used in a number of different applications. It has sulfur in the sulfate form, so it''s all ready to be used by plants. The analysis shows it has 17% sulfur and 22% calcium. It is a little bit slower reacting for a sulfate than say ammonium sulfate or potassium sulfate, but the gypsum works to take out excessive sodium.
