Treatment method for synergic ceramization of electrolytic aluminum overhaul slag
The invention provides a treatment method for synergistic ceramization of electrolytic aluminum overhaul slag. The ceramization process mainly comprises the processes of raw material pretreatment, ball milling, drying, kiln loading, firing, cutting, processing and preparation and the like. The treatment method is combined with the steps in the ceramic process to form a complete self-circulation treatment process, and comprises the steps of 1, sorting the overhaul slag; 2, crushing the waste slag to be treated; 3, sorting the crushed powder; 4, mixing the selected waste slag with other raw materials, and adding a chelating agent for ball milling; 5, drying the obtained slurry to prepare powder; and 6, distributing, calcining, and naturally cooling to obtain a ceramic product. According to the treatment method, the treatment technology combining wet treatment and ceramic preparation is adopted, the problem of safe treatment of dangerous waste slag in the electrolytic aluminum industry is effectively solved, harmless and resourceful treatment of the overhaul slag is achieved, and remarkable economic benefits, environmental benefits and social benefits are achieved.
本发明提供了一种电解铝大修渣协同陶瓷化的处理方法，陶瓷化过程主要有原料预处理、球磨、干燥、装窑、烧成以及切割加工制备等过程。该处理方法结合陶瓷化工艺过程中的步骤、形成完整的自循环处理工艺，包括：1.对大修渣进行分拣；2.对待处理废渣进行破碎；3.将破碎后粉料进行选别。4；将选后废渣与其他原料混合并添加螯合剂进行球磨；5.将所得浆料经干燥处理制粉；6.布料，煅烧，待自然冷却后即得陶瓷化产品。本处理方法采用湿法处理与陶瓷化制备相结合的处理技术，有效解决电解铝产业的危险废渣的安全处置问题，实现大修渣无害化、资源化处理，具有显著的经济效益，环境效益和社会效益。
