Abstract
In the aluminum industries, there are several
steps involved in processing since the extraction of bauxite
to obtain the final product (Al). During the development of
these, various steps generated wastes. One of them, from
the electrostatic filter of the calcination step of the Bayer
process is a very fine black powder, rich in alumina
(Al2O3) that does not meet industry specifications, and it is
discarded in the industry yard. Alumina is a noble material
and has high commercial value. This black powder has
great prospects for recovery, recycling, and future applications.
Therefore, it is important to perform characterization
of tailings and to do that we have used XRD, SEM,
EDS, FTIR, Raman, and thermal analysis.
