Electrolytic aluminum solid waste innocent use technology passed acceptance

Recently, entrusted by the National Development and Reform Commission, Ningxia Autonomous Region Economic and Information Commission organized relevant experts to form an acceptance committee, and passed the project of "National Solid Waste Electrolytic Waste Utilization Technology" project undertaken by China Power Investment Ningxia Energy Aluminum Corporation. Acceptance.

The electrolytic aluminum solid waste innocent use technology project was initiated in May 2007, and was listed in the high-tech industry category supported and developed by the country in August of the same year. The project adopts the grinding-flotation-acid leaching-evaporation process technology to recover high-purity carbon and fluorinated sodium from the waste cathode carbon block; to prepare ultra-fine and wear-resistant through the comprehensive utilization technology of carbonized silicon-silicon nitride refractory bricks material. The total investment of the project is 31,216,100 yuan. At present, a high-tech production line that treats 10,000 tons of spent cathode carbon blocks and 1,000 tons of waste carbonized silicon-silicon nitride refractory bricks has been completed. The research and application of this technology project has reduced environmental pollution, complied with national industrial policies, achieved significant social benefits, and achieved good economic benefits. The integrated utilization of the fixed waste from the electrolytic cell was realized, and the spent cathode carbon block and waste carbonized silicon-nitriding were realized. Silicon brick firebrick integrated recycling industrialization.
