Electrolytic aluminum solid wastes realized harmless utilization

Recently, Ningxia Energy Aluminium Co.,Ltd. and Beijing General Research Institute of Mining and Metallurgy have developed the project of the harmless utilization of electrolytic aluminum solid wastes, and realized industrialization in the Ningxia Energy Aluminium Co.,Ltd.

Through harmless treatment, spent cathode carbon block and other electrolytic aluminum solid wastes can produce carbon powder and sodium  fluoride. By adopting this technology, the Ningxia Energy Aluminium Co.,Ltd. can annually reduces 4,000 tons carbon solid wastes,500 tons  fluoride, 0.4 ton cyanide , 20,000 tons' emission of CO2, and saves 6800 tons standard coal.
