Abstract

Most of the commercial grade aluminium and aluminium alloys containing varying percentages of magnesium (0.5 - 5.0%) are cheap raw materials for superpure aluminium by electrorefining. Since the presence of magnesium will consume the electrolyte of the refining bath and because of the possibility of magnesium depositing in the pure aluminium cathode, prior removal of magnesium is a necessity. Removal of magnesium by air-oxidation, chlorination, chemical treatment and electrolysis have been reported. A suitable fluoride based flux has been formulated and the results of the efficiency of magnesium removal has been discussed and compared with the other results.
