摘要
电解铝生产中产生的碳渣,由于其所含氟化物较多,属于有害固体废物。本文以电解铝工业碳渣为研究对象,研究一种基于浮选-碱浸-碳化法技术的新型冰晶石分离纯化技术,以期达到对冰晶石资源综合利用的目标。
The carbon slag generated in the production of electrolytic aluminum is a hazardous solid waste due to its high content of fluoride.This paper takes the carbon slag of electrolytic aluminum industry as the research object,and studies a new type of cryolite separation and purification technology based on flotation-alkali leaching-carbonization method,in order to achieve the goal of comprehensive utilization of cryolite resources.
