| Abstract: |
| Effects of different kinds of surfactants on leaching process of potassium from phosphorus-potassium associated ore in HCl-H3PO4 media were investigated. The results show that potassium leaching rate rises by 10~15 percent point, reaching 95.01% by adding anionic surfactant (SDS and SLS), while potassium leaching rate drops with addition of cationic surfactant (CTAC) and nonionic surfactant (PEG-6000 and PEG-10000). |
