Polyphosphate Orthophosphate
The wet process requires sulfuric acid to digest the phosphate rock. The resultant phosphate produced by this method is supplied to the agricultural fertilizer industry. The furnace process uses heat to develop a highly purified phosphate rock inside an electric furnace to create phosphorous pentoxide. The phosphorous pentoxide is then ...
