| titleOfInvention | Method for reducing contents of calcium ions, magnesium ions, potassium ions and sodium ions in manganese sulfate |
| abstract | The invention discloses a method for reducing contents of calcium ions, magnesium ions, potassium ions and sodium ions in manganese sulfate. F<-1> in FeF3 can be used for precipitating the calcium ions and the magnesium ions in a solution, Fe<3+> can generate sulfate together with the potassium ions and the sodium ions so as to be precipitated, and Fe(OH)3 formed by hydrolyzing the superfluous Fe<3+> has a remarkable flocculation effect, so that the FeF3 is used as a novel manganese sulfate impurity removal agent; and the calcium ions, the magnesium ions, the potassium ions and the sodium ions are successively precipitated through adjusting the pH value, thus the calcium ions, the magnesium ions, the potassium ions and the sodium ions difficultly separated in common manganese sulfate are separated at one step, and the obtained product can meet the requirement of high-purity manganese sulfate for producing battery-grade or electronic-grade manganese-based raw materials on the contents of the calcium ions, the magnesium ions, the potassium ions and the sodium ions. The method has the advantages of fewer impurity removal agent adding times, simple process, low cost, remarkable impurity removal effect, high purity and obtained manganese sulfate yield and the like, and is easy to produce on large scale. |
