Leached Residue Characterization of Manganese-Bamboo Saw Dust Blend: An X-Ray Diffraction Study

Abstract:

Manganese-bamboo sawdust leached residue (MBLR) is characterized by X-ray diffraction (XRD). The aim of this study is to evaluate the effects of leaching reaction time on the MBLR. The initial solids of low grade manganese (LGMO) ore and bamboo sawdust (BSD) as reducing agent, as well as the leach residues, were characterized. XRD analysis showed that the pyrolusite peak has not been found in the LGMO leached residue and the peak corresponding to quartz and goethite has diminished, compared to XRD peaks of initial LGMO. The calculated crystallinity of the BSD residue has decreased from 56.12% to 52.65%. This indicated that the crystalline portion of cellulose was readily hydrolyzed during the leaching process.
