Phosphate Mining Acid Extraction

  • Role of phosphate and Fe-oxides on the acid-aided .

    A sequential extraction method proposed by Wenzel et al. was employed to determine the changes of chemical forms of As in the soil samples after acid extraction with or without phosphate. For the soils treated with 0.2 M HCl or 0.2 M HCl/0.1 M KH 2 PO 4, rinsing (i.e., 10-min shaking with 1:5 soil to deionized water) was conducted before sequential extraction.

    Propionic acid extraction from the aqueous phase is important in view of its number of uses. The recovery technique should provide high selectivity and yield. A number of techniques like distillation, membrane, dialysis, electrodialysis, and reactive extraction are available. The profound success of reactive extraction has been noted in the recovery of carboxylic acids from dilute solutions.
