| titleOfInvention | Method for producing slag containing two liquid phases and method for producing artificial phosphate ore |
| abstract | The present invention provides a technique capable of effectively separating a steelmaking slag into two liquid phases and advantageously recovering a high phosphorus low iron phase equivalent to phosphorus ore. The phosphorus-concentrated slag contains at least CaO, P 2 O 5 iron oxide and metallic iron, and P 2 O 5 , SiO 2 , iron oxide and metallic iron each contain P 2 O 5 > 7% by mass, SiO 2 2 <10% by mass (including 0% by mass), iron oxide (FeO + Fe 2 O 3 : FeO equivalent) and metallic iron (M.Fe: FeO equivalent)> slag in a composition range satisfying 15% by mass The phosphorus-enriched slag is heated and melted at a heating temperature of 1550 ° C. or higher and held for 10 minutes or longer, so that in the molten state, the upper layer is P 2 O 5 > 25% by mass, iron oxide (FeO + Fe 2 O 3 : FeO equivalent) and metallic iron (M.Fe: FeO equivalent) ≦ 15 mass% high phosphorus phase, lower layer is P 2 O 5 <20 mass%, iron oxide (FeO + Fe 2 O 3 : FeO equivalent) And the sum of metallic iron (M.Fe: FeO equivalent)> 15 It is separated into two liquid phases in an amount percent of high iron phase.
