Calcium Phosphate Process Fluoride Phosphoric Acid dicalcium phosphate process fluoride phosphoric acid A process for producing lowfluorine calcium of hydrochloric acid or by digesting phosphate rock with recycled phosphoric acid and hydrochloric acid to Get Price And Support Online
Dicalcium phosphate is usually prepared by the action of a sulfuric or phosphoric acid upon phosphate rock or other insoluble calcium phosphates and also by the double decomposition of dibasic sodium phosphate with calcium chlorid Thepresent method is simpler than either of the above and is relatively inexpensive
dicalcium phosphate by direct acidulation of phosphate rock In general when phosphate rock is treated with sulfuric acid monocalcium phosphate or phosphoric acid is formed If less sulfuric acid is used dicalcium phosphate should be formed theoretically however only monocalcium phosphate and undecomposed phos phate rock result in practice
