The high iron content manganese which contains 39.05% manganese, 21.28% iron e, 4.79% Si02 and 1.93% CaO, was chemically analyzed (seen in Table 1). The chemical phases and distribution of iron ore and manganese ore are shown in Table 11 and Table III. Table II and Table III show 49.53% manganese exists in the form of isomorphism in iron mineral. 

Iron ores with high manganese content, 5 to 35%, are designated manganiferous ores. They were important in earlier times. Real manganese ores nowadays are ores with a manganese content of at least 35%. They are usually sedimentary and weathered and contain oxide-type manganese minerals.
