Abstract
In this paper the honeycomb like structure MnO was firstly prepared from low grade manganese ore with three main steps Firstly low grade manganese ore was reduced to be MnOby biomass at deg Cin min Secondly the soluble MnO from the reduced low grade MnO ore was leached by dilute sulphuric acid to be MnSO solution at deg Cin min and lastly the honeycomb like structure MnO can be prepared by the redox reaction of mixed MnSO and KMnO solution The optimal experimental conditions were that the pH value of mixed solution was the reaction temperature was deg C the mole ration of KMnO and MnSO was the feed rate of KMnO and MnSO solution was ml min until they were feed out and then kept for min before filtrating The final product was characterized by X ray diffraction XRD and scanning electron microscope SEM demonstrating that its crystal structure was gamma MnO
