Manganese Mining Solution - Mineral Processing

Manganese minerals are weak magnetic minerals (specific magnetization coefficient X=10×10-6~600×10-6cm3/g), can be effectively recovered in a strong magnetic field magnetic separator with a magnetic field strength of Ho=800-1600kA/m (10000-20000oe), and the grade of manganese can generally be increased by 4-10%.

Resources for the future: Seabed minerals and gas

Little exploration for mineral deposits has so far taken place in Norwegian sea areas, and the applicable legislation is not designed for such activity. The MPE is therefore working on a new Act covering mineral recovery from the NCS. Where the NCS is concerned, seabed minerals are known to exist in the deep parts of the Norwegian Sea (figure 8.3).
