THE USE OF COLUMN FLOTATION FOR THE RECOVERY OF ULTRA-FINE PHOSPHATES Harold E. Wyslouzil President - Canadian Process Technologies Inc. Vancouver – BC, Canada Abstract Brazil currently produces around 4.0 Mt per year of phosphate rock, most of which is utilized in the manufacture of phosphate fertilizers.
In production of phosphoric acid, primary purpose of rock phosphate comminution is to expose or create sufficient porous surface area to allow complete dissolution of the rock in relatively short duration at the conditions of acid strengths and temperature prevailing in reactor or attack tanks. Secondary purpose is to reduce power input to agitators in the attack circuits.

The use of phosphate enemas is contraindicated in the setting of any impairment in kidney function. In chronic kidney disease, patients should have their serum phosphorus checked at least at least annually for CKD stage 4 23. When patients are hyperphosphatemic, dietary phosphate restriction and oral phosphate binders should be given.
