The Montedison process is a method used to produce superphosphate through the reaction of ground phosphate rock and sulfuric acid. A by-product of the Montedison process is fluosilicic acid which is either used in the fluorinated compound industry or neutralized and disposed in a landfill. The Montedison process is modified by recycling fluosilicic acid and using it in the den reactor to enhance the reaction between ground phosphate rock and the sulfuric acid. Through this modification, 100 percent of the fluosilicic acid is recycled and thereby reduces disposal costs and the dependence on selling it as a by-product.
