magnetic enrichment of manganese ore

Magnetic Enrichment of Braunite-Rich Manganese Ore at Different .Metamorphism of primary manganese deposits changes the oxi-hydroxide assemblage into a braunite-rich paragenesis. Braunite magnetic properties, together with the increase in grain size during metamorphism, can allow magnetic enrichment at gravel-sand grain size.

Manganese - Wikipedia

The magnes ore did not attract iron, but was used to decolorize glass. This feminine magnes was later called magnesia, known now in modern times as pyrolusite or manganese dioxide. Neither this mineral nor elemental manganese is magnetic. In the 16th century, manganese dioxide was called manganesum.
