【 摘 要 】

Questions about the impact of the metallurgical industry on the environment are increasingly raised in the modern developing world. There are production of harmful gaseous and solid emissions during refining, associated with the use of chloride, fluoride reagents during recycling of aluminium alloys from secondary raw materials on industry enterprises. The using of chlorides, fluorides compounds should be replaced by more environmentally friendly refining reagents or new approaches to production technologies that enable aluminium recycling facilities to meet real-time economic and environmental requirements. The article deals with the problems of the use of existing chloride and fluoride refining compositions, as well as studies and evaluation of highly contaminated remelting aluminium scrap using promising reagents that increase the environmental friendliness of the process. The information and research, incorporated in this article can be extrapolated on the remelting technology of secondary metallized aluminium raw materials in industrial metallurgical units.
