The dissolution behavior of hematite in 1-10 M LiOH, NaOH and KOH solutions was investigated at 303-349°K. The solubility of hematite increased with increasing temperature and alkali hydroxide concentration, although it remained very low. The solubility changed greatly depending on the kind of alkali hydroxide used, in the order NaOH > KOH > LiOH.
