Spent Linings from Aluminum Cells as a Raw Material for the Metallurgical, Chemical, and Construction Industries

摘要

Large quantities of spent cathodic linings have accumulated on the grounds of Russian aluminum plants and at adjacent disposal sites, these linings being comprised of metallized and fluoride-impregnated carbon-graphite materials and refractories. It is of interest from both a scientific and an engineering standpoint to find ways to recover the valuable components in these wastes and use the recycled materials in different industries. A pyrometallurgical method is proposed for recycling the wastes with the use of standard equipment, and the physicochemical properties of waste materials collected from decommissioned aluminum cells are determined.
