hydrochloric acid may be used to selectively leach out the calcareous materials from low grade phosphate rock rather than the dissolution of apatite. In this work, the suitability of dilute hydrochloric acid has been studied to leach out the calcareous and dolomitic gangue materials from the indigenous low grade phosphate rock.
efficient and economical route for manufacturing phosphoric acid by treating rock phosphate with commercial hydrochloric acid followed by its separation from the crude mixture by solvent extraction using amyl alcohol as solvent. The acid, obtained by this method, is of high quality and could be upgraded up to density of 1.5 g/mL at 25 °C.

21. Why doesn't the stomach digest itself? A. The stomach wall lacks proteins so enzymes won't attack it. B. The digestive enzymes in the stomach aren't efficient enough. C. The stomach lining is too tough to be digested. D. The stomach wall is protected by large amounts of mucus. E. The stomach is protected by HCl.
Potentially harmful phosphate-based products derived from the wet acid digestion of phosphate rock represent one of the most serious problems facing the phosphate industry. This is particularly true for dicalcium phosphate (DCP), a food additive produced from either sulphuric acid or hydrochloric acid digestion of raw rock material.
Both batch and bench-scale continuous tests were made. Western phosphate rock concentrates were acidulated with hcl, and the digestion liquors were processed by solvent extraction. Phosphoric acid was extracted with isoamyl alcohol and recovered from the organic extract by contact with an nh4f solution.
