The precipitation mode of barium sulphate (BaSO4) in the presence of mineral additives plays an important role in many industrial processes. Therefore, in this paper, a study of the precipitation reaction of a saturated barium sulphate solution in the presence of metal ions Fe3+ and Mn2+, found in industrial waters and in the geochemical evolutions of paleoenvironments, is presented. XRD, conductivity, FTIR spectroscopy, and SEM were used to investigate the barite precipitation reaction in the presence of a known amount of Fe3+ and Mn2+ ions. Conductivity measurements showed that the presence of Fe3+ accelerated both induction and crystal growth stages. On the other hand, adding Mn2+ ions did not affect the kinetics of the precipitation reaction. Solid analysis showed that the barite lattice was doped with low levels of manganese.
