| titleOfInvention | Method for purifying and removing iron, aluminum and silicon in superimposition manner |
| abstract | The invention belongs to the technical field for purifying and removing iron, aluminum and silicon by utilizing a cobalt (nickel) salt solution, and particularly relates to a method for purifying and removing the iron, aluminum and silicon in a superimposition manner. The invention discloses a method for purifying and removing the iron, aluminum and silicon in the superimposition manner. The method comprises the following steps of A, leaching; B, superimposing a filter liquid and a precipitation agent and adding the mixture into an iron-removal settlement tank to be dispersed and diluted through a stirring impeller; C, extracting through diisooctyl phosphate; D, extracting through mono(2-cthylhexyl)2-cthylhexyl phosphonate; E, adding acid into the extraction liquid to be reacted under the room temperature, standing the reaction liquid to be layered, wherein the upper layer is the extracting agent and solvent oil, the lower layer is a cobalt sulfate solution, and the cobalt sulfate solution can be directly concentrated and crystallized to be packed into a finished product. The entire process flow is reasonable, the device is convenient and easy to control, the energy consumption is low, and the environmental pollution can be avoided. |
