| Abstract: | A so-called “One high and four lows” aluminum smelting technology(high cell voltage, low Al-2O-3 concentration, low mole ratio, low AE coefficient and low electrowinning temperature) is proposed based on comprehensive research on process conditions, such as cell voltage, mole ratio, electrowinning temperature and AE coefficient by using point charging of Al-2O-3 and controlling Al-2O-3 concentration. The results of comparison with the conventional process show that it is possible to improve current efficiency by a big margin and reduce power consumption by using this new technology. |
