Abstract
The invention relates to metallurgical production, and more particularly to preparing a charge ingot which is used for producing bronze ingots by casting. As a starting charge material, a spent inert anode previously used in the electrolytic production of aluminium is utilised, that is covered with alumina, allowing same to react with a bath which flows out of the anode during a thermal treatment performed at a temperature within a range of 950-1200° C., followed by soaking in a furnace for at least 3 days. The invention makes it possible to obtain a charge ingot with a minimal electrolyte content.
