摘要： A start-up process of making aluminum using a single carbothermic reactor/furnace (11) having a single hollow reactor compartment with bottom resistance heating electrodes (16) (13) in the side of the reactor, involves adding Al 2 O 3 and C (carbon) for start-up and melting the mixture to provide a (Al 2 O 3 -Al4C 3 ) slag having a temperature between about 1875°C and 2000°C; and then adding Al4C3 to the slag and raising the temperature of the furnace (11) to form a top Al phase with 6 to 8 wt% C (21) and a bottom slag phase (22); and then adding Al 2 O 3 is added to the Al-C/slag (21, 22) to produce an Al 2 O 3 rich slag lower the reactant temperature and produce a decarbonization reaction (step 30) providing a top Al phase with less than 5 wt% C (23) which is then tapped after step (40). The remaining slag is the starting material.
