[0002] Iron powder reduction is an important chemical reduction method, and has a wide application in many industrial fields. In the metallurgical industry, it is commonly used to extract metals from metal oxides. For example, using iron powder to reduce some metal oxides into elemental metals provides raw materials for subsequent refining processes. In chemical production, iron powder reduction can be used to synthesize various organic compounds, such as the production of some pharmaceutical intermediates, dye intermediates, etc. By reducing compounds containing specific functional groups, their chemical structures can be changed to obtain the desired products. The application of this process is of key significance to meet the needs of different industries for metal materials and chemical products.
