Recently, the construction of “Qingtongxia Aluminum Co., Ltd. to treat 4,000 tons of electrolytic aluminum waste cathode carbon block annually†was carried out under the auspices of the Qingtongxia Energy Aluminum Corporation Science and Technology Information Center of Ningxia. The main process of the no-load on-line test was successful. At the beginning of August, trial production was started.
The project is a major technological innovation industrialization project that has been approved by the National Development and Reform Commission for the purpose of recycling the solid waste generated in the electrolytic aluminum production process. The project adopts flotation-acidolysis combined process technology to treat waste cathode carbon material, so that the carbon recovery rate reaches 95.90%, and the fluorine recovery rate reaches over 93.89%. At the same time, the waste gas and waste water produced in the process are treated with environmental protection.
After the project is completed and put into production, it not only can effectively protect the environment and solve the key common technical problems in the development of China's electrolytic aluminum enterprises - reducing solid waste efflux and energy consumption of electrolytic aluminum, but also can achieve comprehensive utilization of resources for the development of China's electrolytic aluminum industry and other Related industries play a role in demonstration and promotion, with significant social and economic benefits.
During the construction of the project, leaders at all levels of the company attached great importance to the construction of the project, and put forward specific requirements for the importance of the project, during the construction of the pilot line, and during the later period of management. With the coordination and cooperation of the company's production technology department and the production units of the Qing aluminum company, the planning and operation department, the safety and environmental protection supervision department, and the dynamic branch companies, the preliminary design, environmental assessment, and equipment of the project have been successfully completed. Material procurement and other work.
