| titleOfInvention | Method for preparing high purity potassium carbonate and high purity aluminium hydroxide through Baiyun ebo potash feldspar concentrate |
| abstract | The invention relates to a method for preparing high purity potassium carbonate and high purity aluminium hydroxide through Baiyun ebo potash feldspar concentrate, and belongs to the field of hydrometallurgy. According to the present invention, the potash feldspar concentrate is adopted as a raw material, wherein the potash feldspar concentrate is sorted from the Baiyun ebo potassium-rich slate, and has the purity more than 95%; the new process adopts lime sintering and stepwise leaching method for preparing the high purity potassium carbonate and the high purity aluminium hydroxide. The purity of the potassium carbonate is more than 99%, the recovery rate of the potassium carbonate is more than 90%; the aluminium hydroxide meets the state grade 1 standard, and the recovery rate of the aluminium hydroxide is more than 85%; the process provided by the present invention is simple, the method is applicable for the industrial production, and good economic benefits are provided. |
