Phosphate Rock Digestion With Hydrochloric Acid

When phosphate rock is leached with hydrochloric acid, radium can be removed by co‐precipitation with Ba 0.4 Ca 0.6 SO 4 and uranium by extraction with a 5% solution of tributyl phosphate in hexane or Varsol. Phosphoric acid is then separated from calcium chloride solution and other impurities by extraction with undiluted tributyl phosphate.
We have 40 years of experience in mechanical manufacturing and provide you with the most sophisticated equipments.

Treatment Of Phosphate Rocks With Hydrochloric Acid ...

Jul 17, 2010 Phosphate rocks were leached with hydrochloric acid; and radium was removed by co-precipitation with BaSO4. Uranium and lanthanides were extracted by di(2-ethyl hexyl) phosphoric acid and tributyl phosphate. Phosphoric acid was then separated from calcium chloride solution and other impurities by extraction using undiluted iso-amyl alcohol.

About 15 ml of 70% perchloric acid is added to the beaker and allowed to fume off for half an hour in the fuming cupboard (under a fume hood). Digestion of the mass with perchloric acid enables the dissolution of most metal perchlorates easily in hydrochloric acid. Moreover, dilute perchloric acid does not cause an interference when used in AAS.
