摘要： The present invention belongs to the field of comprehensive utilization of resources, in particular to a method for preparing a metal-organic framework (MOF) material by using metallurgical mine solid waste. The method uses concentrated strong acid or strong alkali to dissolve the metallurgical mine solid waste to obtain mixed metal salt. An organic matter is used as an organic ligand. The mixed metal salt and the organic ligand are dissolved in an organic solvent. The mixture is kept at a constant temperature of 70-150°C for 18-30 h, thus synthesizing an MOF material. The present invention provides a new method for preparing the MOF material containing valuable metal elements by using the metallurgical mine solid waste. Raw materials are readily available; metallurgical slag containing valuable metal elements, minerals, dust, and other waste metal alloys can be effectively exploited. The synthesis method is simple, and synthesis conditions are mild. The method is applicable to comprehensive utilization of the metallurgical slag, the minerals, the dust, and the waste metal alloys.
