Assessment of iron ore mineral wastes for sulfate removal ...

From the predicted model, maximum sulfate adsorption onto metasomatite and quartz-albitophire was 31.07 and 20.27 mg g −1, respectively. This adsorption rate indicates that the seemingly worthless iron ore mineral waste can be useful to eliminate one of the most hazardous environmental pollutants.
