Abstract: To reduce energy consumption, the physicochemical properties of NaF-AIF3-BaC12-NaCI system were systematically studied. The mathematical models of the liquidus temperature andelectrical conductivity were obtuined and the density was also studied about this system-Basedon these experiments, three groups of energysaving electrolyte composition were proposed.This achievement has been applied in the aluminium refining industry, and it was demonstratedthat the energy consumption was reduced by 1 200 kWh per ton of refined aluminium.
Key words: Aluminium refining electrolyte energy-saving
