Resource utilization method of electrolytic manganese residues
The invention relates to the technical field of waste recycling, in particular to a resource utilization method of electrolytic manganese residues. According to the method, precious metal ions such as manganese, cobalt and nickel in the electrolytic manganese residues are extracted through an acid leaching method, then secondary waste residues obtained through acid leaching and waste biomass residues are mixed and sintered, in the sintering process, components (mainly including silicon dioxide and iron oxide) of the secondary waste residues hardly react, and the integrity of a structural body is kept; and after the biomass slag mainly composed of carbon reacts, a porous structure is formed macroscopically and microcosmically, so that the impedance matching is improved while the material quality is reduced. Therefore, according to the resource utilization method provided by the invention, the precious metal in the electrolytic manganese residues is recycled, and meanwhile, the light and efficient electromagnetic wave absorption building material is prepared.
本发明涉及废物再利用技术领域，具体涉及一种电解锰渣的资源化利用方法。本发明先采用酸浸法提取了电解锰渣中锰、钴、镍等贵金属离子，随后将酸浸得到的二次废渣与废弃生物质渣混合后，烧结，烧结过程中二次废渣本身成分(以二氧化硅、氧化铁为主)几乎不反应且保持了结构主体完整性，而主要由碳组成的生物质渣反应后，在宏观和微观上都形成了多孔结构，降低了材料质量的同时还提高了阻抗匹配。因此，本发明提供的资源化利用方法在回收了电解锰渣中贵金属的同时，还制备了轻质、高效的电磁波吸收建筑材料。
