Separation of Magnesium Hydroxide and Barium Sulphate from a
... In the previous section it was shown that Mg(OH)2 can be dissolved by the formation of Mg(HCO3)2, through CO2 addition without affecting the low solubility of BaSO4. The sludge separation process will be more effective at higher solubility values for Mg(HCO3)2. Therefore, it was decided to determine ...
