Comprehensive utilization of carbide slag

Abstract：According to the chemical property of carbide slag, this paper discusses the synthetically using methods in three aspects. First, it can be used as construction materials, such as in fire cement. Second, it can be used as chemical materials, for an example, for potassium chlorate production instead of lime. Thirdly, it can also be used to solve environmental problems, such as extinguish materials when coal gangue mountain autoignites, and also for acid waste water treatment or as sulfide fixation agentia when coal burns.
