| Abstract: | In order to study using the macromolecular caramel in the molasses alcohol wastewater to leaching the manganese from a low grade pyrolusite,the shrinking core model was used to investigate the kinetics of the manganese reductive leaching process in dilute sulfate acid.Since the salvage of only the macromolecular caramel from the molasses alcohol wastewater is very difficult,in this study the synthesized caramel was used to simulate it.The effects of reaction temperature,the concentrations of H2SO4 and caram... |
