Abstract
Procedure for the manufacture of alumina that allows the use of the low oven, using a low oven blown with super-oxygenated cold air to obtain a slag containing alumina and aluminum sulfide that is later decomposed by hydrolysis, characterized by the proportion of pyrite in the load, the smaller the diameter of the lower furnace at the level of the nozzles and the more silica the load elements contain.
