Manganese - Wikipedia

Manganese(IV) oxide (manganese dioxide, MnO 2) is used as a reagent in organic chemistry for the oxidation of benzylic alcohols (where the hydroxyl group is adjacent to an aromatic ring). Manganese dioxide has been used since antiquity to oxidize and neutralize the greenish tinge in glass from trace amounts of iron contamination.

Hidden gold in manganese - The Treasures Of Utah

Manganese has the ability of disolving gold when in contact with ground mineral waters. The gold is locked up in the manganese and when the spring water enriched manganese comes in contact with iron, any gold it's carrying will precipitate out into the iron (leach out).
