Wet Process Phosphoric Acid
Published: August 1982
In this study, we have examined the technology and economics of the three WPPA routes in commercial use--dihydrate, dihydrate/hemihydrate, and hemihydrate. The economics of solvent extraction to purify WPPA to industrial grade has been updated and compared with the economics of making furnace phosphoric acid in a new plant. Lastly, we have evaluated uranium recovery from WPPA.
