11.21 Phosphate Rock Processing - US EPA

2015-9-10  Alternative process flow diagrams for phosphate rock processing.The wet beneficiated phosphate rock may be dried or calcined, depending on its organiccontent. Florida rock is relatively free of organics and is for the most part no longer dried or calcined.The rock is maintained at about 10 percent moisture and is stored in piles at the mine and/or chemicalplant for future use. The rock is slurried in water and wet-ground in ball mills or rod mills at thechemical plant. Consequently, there is no significant emission potential from wet grinding. The smallamount of rock that is dried in Florida is dried in direct-fired dryers at about 120°C (250°F), where themoisture content of the rock falls from 10 to 15 percent to 1 to 3 percent. Both rotary and fluidizedbed dryers are used, but rotary dryers are more common. Most dryers are fired with natural gas orfuel oil (No. 2 or No. 6), with many equipped to burn more than 1 type of fuel. Unlike Florida rock,phosphate rock
