| Abstract: | Potassium leaching rate reached 95.62% through leaching hydromica-shale in sulfuric acid and fluosilicic acid system with low temperature(105 ℃) hydrometallurgical process.Potassium was recovered by adding fluosilicic acid into leaching solution,and its recovery reached 95.47%.The final total recovery of potassium reached over 90%,and the content of K2SiF6 in potassium fluosilicate product reached over 98%.SiF4 gas produced from leaching process in sulfuric acid and fluosilicic acid system was adsorbed by absorption bottle to generate white carbon black sediment and fluosilicic acid solution,which can be recycled to significantly reduce the cost. |
