Sustainable Mining and Metallurgy

In the conventional aluminum electrolytic cell, the production of 3N refined aluminum by molten salt electrolysis was carried out by using high-quality raw material and auxiliary materials, optimizing technological conditions and fine operation management, and the problems existing in the experiment were discussed. and problems in the test were discussed. The results show that the content of impurity elements in the aluminum solution decreases in varied degrees, and the quality of the aluminum solution reaches the standard of 3N aluminum, which indicates that it is feasible to produce 3N refined aluminum by Molten Salt electrolysis. The cost of 3N Aluminum production by molten salt electrolysis is reduced substantially compared with conventional method.
