Sustainable Mining and Metallurgy

Many electrolytic aluminum enterprises use a large number of alumina rich in Li and K for production. Li and K enrichment significantly change some physical and chemical properties of the electrolyte, affecting electrolysis production. This paper discussed the effects of LiF and KF on the physical and chemical properties of electrolyte phase, primary crystal temperature, conductivity, density, dissolution loss of aluminum and dissolution of alumina, as well as the influence on aluminum electrolysis production. In view of the influence of Li and K enrichment on aluminum electrolysis production, relevant production technical measures were summarized.
