Slag melting method
The invention relates to the technical field of furnace slag treatment, and discloses a furnace slag melting method which comprises the following steps: S1, furnace slag classification: classifying generated furnace slag, and distinguishing according to components and properties of the furnace slag; s2, slag crushing: mechanically crushing the slag to enable the particle size of the slag to be moderate; s3, magnetic separation: carrying out magnetic separation on the slag by using magnetic separation equipment to separate out iron components in the slag; and S4, phosphorylation treatment: carrying out phosphorylation treatment on the slag containing phosphorus minerals, and combining phosphoric acid with the phosphorus element in the slag to form phosphate, thereby reducing the emission of phosphorus. Through the steps of slag classification, crushing, magnetic separation, phosphorylation treatment, desulfurization, activation, solidification and the like, the slag melting treatment efficiency and the resource recovery rate are improved, and valuable elements such as iron and aluminum in the slag can be recovered, so that comprehensive utilization of resources is achieved, and dependence on natural resources is reduced.
本发明涉及炉渣处理技术领域，公开了一种炉渣化渣的方法，包括以下步骤：S1、炉渣分类：对产生的炉渣进行分类，根据其成分和性质进行区分；S2、炉渣破碎：将炉渣进行机械破碎，使其颗粒大小适中；S3、磁选分离：利用磁选设备对炉渣进行磁选分离，分离出其中的铁质成分；S4、磷酸化处理：对含磷矿物的炉渣进行磷酸化处理，将磷酸与炉渣中的磷元素结合形成磷酸盐，减少磷的排放。通过炉渣分类、破碎、磁选分离、磷酸化处理、脱硫、活化和固化等步骤，不仅提高了炉渣化渣的处理效率和资源回收率，还能实现炉渣中有价值元素的回收，例如铁、铝等，从而实现资源的综合利用，降低对自然资源的依赖。
