| titleOfInvention | Efficient method for recovering valuable metals from steelmaking slag |
| abstract | An object of the present invention is to improve the recovery rate of iron-manganese oxide recovered from slag. A method of recovering valuable metals after performing a metal removal process for removing metal from a steelmaking slag containing a CaO—SiO 2 —P 2 O 5 phase and a (Fe, Mn) Ox phase. Thus, the basicity becomes 1.5 to 2.5 within a temperature range of 1250 to 1400 ° C. for steelmaking slag having a basicity of less than 1.5 after the treatment or steelmaking slag having a basicity of more than 2.5. The steelmaking slag that has been subjected to the reforming process and subjected to the metal removal process and the reforming process is pulverized so that the representative particle size after pulverization is 50 μm or less, and the slag after the pulverization process is roughened. In the classification process of classifying into fine particles and fine particles, the ratio of the representative particle size of the coarse particles to the representative particle size of the fine particles is processed to be 2.5 times or more, and the coarse particles are recovered after the classification treatment. is there.
