Processing method for comprehensive utilization of coal ash and slag resources
The invention discloses a coal ash and slag resource comprehensive utilization processing method, which belongs to the technical field of coal ash and slag reutilization, and comprises the steps of raw material pretreatment, screening and classification, mixing treatment, digestion and aging, compression molding, and drying and shaping. According to the processing method for comprehensive utilization of coal ash and furnace slag resources, the furnace slag and coal ash are processed through the processes of raw material pretreatment, screening and classification, mixing treatment, digestion and ageing, compression molding, drying and shaping and the like, metal contained in the furnace slag and furnace ash is extracted through the steps of flotation, magnetic separation, leaching and refining, and the metal content in the furnace slag and the furnace ash is reduced. By arranging the steps of mixing treatment, digestion and ageing, compression molding and the like, the residual fixed materials are made into bricks, so that the slag and the coal ash are utilized for many times.
本发明公开了一种煤灰和炉渣资源综合利用加工方法，属于煤灰炉渣再利用技术领域，包括原料预处理、筛选分类、混合处理、消解陈华、压制成型和烘干定型；本发明所提出一种煤灰和炉渣资源综合利用加工方法，通过设置原料预处理、筛选分类、混合处理、消解陈华、压制成型和烘干定型等工艺对炉渣和煤灰进行加工处理，通过设置浮选、磁选、浸出和精炼步骤，对炉渣和炉灰中含有的金属进行提取，通过设置混合处理、消解陈华和压制成型等步骤，对残留的固定进行制砖，实现了炉渣和煤灰的多次利用。
