摘　　要：目前生产铝最常用的方法是电解法,它的原理就是以氧化铝为初始原料、熔融冰晶石(Na_(3)AlF_(6))为溶剂,在电解槽内进行电解得到熔融铝液。但是在电解法冶炼金属铝的过程中会产生一种名为碳渣的废弃生成物。本文对铝电解质碳渣的固废资源化利用进行了研究,在分析目前大多数铝厂碳渣焙烧处理方法的基础上,进一步确定出了更合适的工艺参数(焙烧温度、粒度)。At present,the most-commonly used method to produce aluminum is electrolysis.Its principle is to use alumina as the initial raw material and molten cryolite(Na_(3)AlF_(6))as the solvent to produce molten aluminum through the electrolytic process in the pot.However,during the electrolytic process for aluminum production,a kind of waste product called carbon slag will be produced.In this paper,the solid waste resource utilization of aluminum electrolyte carbon slag is studied.Based on the analysis of the current baking methods of carbon slag in most aluminum smelters,the more appropriate process parameters(baking temperature and particle size)are further determined.
