摘要
碳渣是铝电解生产过程产生的有害废物,碳渣中含有大量的氟化盐,采用浮选法对碳渣中的氟化盐进行回收利用,不仅可以减少氟化盐的损失,提高资源的利用率,还避免了对环境的污染,该方法具有显著的经济效益和社会效益。
Carbon slag is a harmful waste in electrolytic Aluminium production process. In the carbon slag contained a lot of fluoride, applied flotation process can recover fluoride in carbon slag, it not only decrease loss of fluorid and increasing utilization and avoid enviromentle pollution. Remarkable econoic and social benefits have been obtained in this method.
