Abstract

Ferrous sulfate is usually produced from the spent pickling liquor when the metal sheets are pickled in the processing of steel. In the present work ferrous sulfate was prepared by simple acid leaching method by using waste condensed milk can as a raw material. This can contains around 87 percent of iron which was successfully converted to greenish crystals of ferrous sulfate by simple acid leaching followed by crystallization. The process parameters like concentration of acid, molar ratio of iron to acid, period of reaction,effect of temperature and effect of occasional stirringwere optimized. Nearly 98% iron was leached out from iron containing can and converted to ferrous sulfate. The product was characterized by chemical analysis, thermo gravimetric analysis and X-ray diffraction analysis. On chemical analysis it was found that the produced product is highly pure, nearly 97 percent. According to the DSC/TGA studies, it is found that the prepared sample is hexahydrate. From X-ray diffraction pattern, it was confirmed that the prepared sample is ferrous sulfate with melanterite phase and have monoclinic crystal structure.
