抄録

To study on the reducibility of some manganese ores which are used for ferromanganese production, we investigated their properties in the first place. We obtained the following results of X-ray diffraction, differential thermal analysis and thermal balance analysis.<BR>(1) Foreign ores are mostly MnO2 ores, and their attendant minerals are MnO·OH, 3Mn2O3·MnSiO3, hydrated Mn oxide, SiO2, etc. MnO2 ores have α-, β-, γ- and/or δ-phases and most of them are these mixtures.<BR>(2) In every MnO2 ore, γ- and δ-phases are incompletely crystalline, and they are reduced to Mn2O3 or Mn3O4 easily at comparative low temperature. Ghana ore, which is γ-MnO2, belongs to the above group, and is expected to have high reducibility.<BR>(3) Domestic ores are mostly manganese carbonate ores or silicate ores, and mineral compositions of burnt ores represent variations in the burning temperature and atmosphere.<BR>(4) Quantitative studies on such mineral compositions will be continued futhermore.
