| titleOfInvention | A method for treating waste sulfuric acid |
| abstract | Waste sulfuric acid together with the oxidenmagnesium is added to the hot suspensionnmetal oxides from the previous operationnintensive mixing and oxidation supplynair. The reaction proceeds at a temperature of 70 ° Cn80 eC and the pH is maintained between 3.5 and 4.5.nUnder these conditions, neutralization occursnand oxidizing the brown mixed oxide with predominancenferric oxide and up to 36% sulphate solutionnof magnesium. The resulting suspension was separated and concentratednthe mixed oxide is treated by known methodsneither to filler or to less quality brownnpigment. The liquid phase is worked up tonsolid magnesium fertilizer, optionally after additionnurea to liquid nitrogen and magnesiumnfertilizer. From the magnesium sulfate solutionnit is possible to granulate in natural monohydratenmagnesium sulphate - kieserttem -nto prepare a solid magnesium fertilizer, thereby eliminating itncostly evaporation of water. |
