| titleOfInvention | Method for producing high phosphorus content slag and slag fertilizer and phosphate fertilizer |
| abstract | Provided is a production method for obtaining a high phosphorus content slag that can be easily used as a phosphorus resource from steelmaking slag. A first step of reducing steelmaking slag containing phosphorus generated in a steelmaking refining process, reducing iron oxide in the steelmaking slag and recovering it as phosphorus-containing molten iron, and the first step The phosphorus-containing molten iron obtained in the step is dephosphorized, and the high phosphorus slag obtained is recovered, and the high phosphorus slag obtained in the second step is heated to a temperature of 1500 ° C. or higher. Separating the two-liquid phase and recovering the ultra-high phosphorus slag in the upper layer, and the ultra-high phosphorus slag obtained in the third step as it is or at least one of magnetic ore separation, floatation or specific gravity separation One method is implemented, and a high phosphorus content slag is manufactured through the 4th process of obtaining the slag containing 30 mass% or more of phosphoric acid and less than 10 mass% of iron content (Fe conversion).
