This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 Excerpt: ...morning the liquor is analyzed and the amount of lime necessary for the completion of the reaction added as before. After standing again the results are checked up by a third analysis of the liquor, and if found correct, the liquor is drawn off and the precipitate washed and dried. Instead of using the titration method described in Chap. IX, conductivity determinations may be substituted but they take somewhat longer and variations in the amount of other soluble salts present introduce an unknown error. If a distinctly acid phosphate is being produced, the phosphate remaining in the liquor drawn off may be precipitated by lime and the precipitate produced added to the liquor for the next batch without any washing or further treatment. As before stated, washing increases the alkalinity of the precipitate and, therefore, only the minimum amount of wash water necessary to remove the undesirable soluble salts should be used. The leach liquors may be converted into phosphoric acid according to the reaction: Ca(H2P04)2 +H2S04-CaS04 + 2H3P04 by the addition of sulphuric acid. If a high percentage of hydrochloric acid is present, it may be distilled off after concentration, or even distilled off before the addition of the sulphuric acid.
