摘要：

Xinjiang Join-World Co. Ltd. is the largest producer in China and an important one in the world for refined aluminum and high-purity aluminum. At present, 99.99-99.999% refined aluminum is produced by 80kA three-layer electrolysis cells (XJ-80) with the Gadeau process electrolyte system and solid refined aluminum cathode. The current efficiency is up to 99%, DC power consumption 12000kWh/t refined aluminum. The XJ-80 cell is also the largest one in aluminum refining industry in the world. High-purity aluminum of 99.999-99.9999% purity is yielded by the combined technique of three-layer electrolysis and segregation method. Super high-purity aluminum in excess of 99.9999% is produced by the new combined technique of ionic liquid electrolysis and zone refining method. This paper introduces these characteristics of the XJ-80 three-layer electrolysis cell, the combined technique of three-layer electrolysis and segregation method and the new combined technique of ionic liquid electrolysis and zone refining method for producing high-purity aluminum.
