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.en-USrestritoBayer processIndustrial wasteBlack dustThermal analysisArtigo publicado em periodicohttps://link.springer.com/article/10.1007/s10973-011-1830-0https://doi.org/10.1007/s10973-011-1830-0
