説明

Chuo Denki Kogyo Co. Ltd. was established for producing low cation ferromanganese in February 1934. Now our company produces some ferromanganese, electrolytic manganese, and inorganic compounds of manganese. The electrolytic manganese is produced at Taguchi Plant of Myokokogen in Niigata.<BR>Commercial production begun in 1940 was small, of the order of 15 kg per day, and the process was gradually improved and the pilot plant expanded so that it had a monthly capacity of 300 tons in 1971.<BR>Initially native Rhordochrosite (MnCO3) was used as manganese source. But it was changed to calcined ore of manganese dioxide (MnO2) in 1976. The reduction process has been originally studied to develop new sources of the metal. Use of the calcined ore has an advantage to maintain the stability of the operation.
