Di-calcium phosphate by direct acidulation of phosphate rock

di-calcium phosphate by direct acidulation of phosphate rock. In general, when phosphate rock is treated with sulfuric acid, mono-calcium phosphate or phosphoric acid is formed. If less sulfuric acid is used, di-calcium phosphate should be formed theoretically, however only mono-calcium phosphate and undecomposed phos­ phate rock result in ...

Jul 08, 2011  In addition to providing you with calcium, calcium carbonate is also an antacid and helps to neutralize excess stomach acid. As such, many over-the-counter antacids, including Tums and Rolaids, double as calcium supplements. Calcium phosphate has no such antacid properties, so it serves only as a calcium supplement. 00:00.
