manganese extraction from its economic ores in brunei

For example almost half of the manganese ore resources in India are ferruginous and more than 73 of the manganese ores in China belong to FeMn ores with a low MnFe mass ratio 3 With the depletion of high grade manganese ore resources the FeMn ores are becoming important substitution resources for extracting manganese...
