Disclosed herein are methods for producing an aluminum-scandium alloy comprising 0.41-4 wt % of scandium which can be used in industrial production setting. The method is carried out by melting aluminum and a mixture of salts comprising sodium, potassium and aluminum fluorides followed by performing simultaneously, while continuously supplying scandium oxide, an aluminothermic reduction of scandium from its oxide and an electrolytic decomposition of the formed alumina. Periodically, at least a portion of the produced alloy is removed, aluminum is then charged, and the process of alloy production is continued while supplying scandium oxide. Also disclosed is a reactor for producing an aluminum-scandium alloy pursuant to the methods described herein.

An apparatus, also named transfer box or TB, for conveying an anode assembly outside of an electrolyte cell is described. An apparatus, also named cell preheater lifting beam or CPLB, for conveying an anode assembly or a cell pre-heater outside of an electrolyte cell is also disclosed. TB and CPLB are conjointly used for starting up the electrolytic cell or for replacing a spent anode assembly while maintaining the production of non-ferrous metal, such as aluminum or aluminium. The thermal insulation of the TB allows maintaining the anode temperature homogeneity and preventing thermal shocks when introducing the inert anodes into the hot electrolytic bath. TN and CPLB allow accurate positioning of anode assemblies or cell-preheaters over the electrolysis cell before achieving mechanical and electrical connections of the anode assembly or the cell pre-heater to the electrolysis cell. Several related methods for the operation of an electrolytic cell are also disclosed.
